So almost anything goes? Hehehe.. >
The map locations were there just for the storyline feel. They could probably all be standing next to each other in the same room and still work, haha. The NPC names are random and I'm also not sure if these could all be done in game, but here goes:
Storyline: A researcher visiting Pallet Town is requesting assistance because he is studying the origins of Eevee's mysterious evolutionary power. Your mission involves a series of tasks in order to help him uncover evidence to support his thesis that Eevee were once common in the southern areas of Kanto and it gained the power to evolve into various Pokemon due to the large change of environments it migrated over in the ancient past.
NPC: Researcher Evan
Location: Pallet Town
Dialogue:
Hello trainer! I'm researching the evolutionary properties of Eevee, and I'm convinced that Eevee is able to evolve into multiple Pokemon because it migrated and adapted to different environments. Would you like to help me on my research?
(yes or no choice) If yes-
Excellent! I have a theory that Eevee were once common around Cinnabar Island, Seafoam Islands, and parts of Kanto. However, to aid in my research I need you to obtain 5 pieces of Evolution Evidence (<-- that's an item) for me. I have other assistants assigned to do fieldwork there and I would like you to help me collect the Evolution Evidence from them. You should head off to Cinnabar Island first. One of my assistants should be studying near the volcano.
NPC: Assistant Gregory
Location: Cinnabar Volcano Cave
Dialogue:
Ah I see, you're helping Researcher Evan! I'm here gathering evidence that the Eevee originally lived on this island before expanding to other regions. How do I know this? It's because this island was the only source of fire stones in Kanto, and ancient lava floes showed Eevee foot prints in the rocks. But I'm missing one more key piece of evidence! In order for Eevee to evolve in the wild naturally, they need to have been exposed to Fire Stone material. I'm thinking that a certain self-destructing rock-type pokemon was able to detonate and release Fire Stone Shards trapped in the rocks. I need you to give me 10 of these Firestone shards by battling the wild Graveler.
(Firestone shards should be an uncommon drop from defeating wild Gravlers in the cave)
(Then you talk to Assistant Gregory again after you collect all 10)
So I was right! The Graveler was able to release the shards from the rocks in order for Eevee to evolve into Flareon! I suppose the massive volcanic activity over the decades wiped out most of Eevee's habitat here.. But my part of the research is now complete. Please give this Evolution Evidence to Researcher Evan! I think you should talk to my co-assistant who is somewhere in the Seafoam Islands.
(You gain an Evolution Evidence Item)
NPC: Assistant Rianne
Location: One of the random Seafoam island maps
Dialogue: (this person also won't intiate the quest unless you have 1 evolution evidence item in your possession)
Oh, I see you spoke to Assistant Gregory! I'm researching these islands because we believe that Eevee adapted to these islands from the population on Cinnabar Island. We've found evidence of Water Stone shards deep within the cave, and ancient skeletons of Vaporeon in these caves as well! It would make sense for the Eevee here to adapt a water evolution because the sea is the only place to obtain food here. I had all the evidence but I need one more. There is a Pokemon here -a Staryu- that also evolves when exposed to a Water Stone. Would you be able to capture a Staryu here for me to look at?
(yes or no choice) If yes:
Thank you! Staryu are rare these days but it's not impossible to find one!
(The quest should be set so that only Staryu caught after the quest is initiated counts. So go catch a Staryu and take it to the guy)
I see, this Staryu is intriguing. May I ask you to evolve it into Starmie for me as well?
(Evolve that Staryu to Starmie)
That's perfect! My research here is complete! The evolution to Vaporeon probably made the Eevee line strong enough to swim to the mainland of Kanto. Speaking of which, here is my Evolution Evidence. My fellow researcher is at Fuschia City rigth now near the Safari Zone. He's studying Eevee of the mainland.
(You recieve another Evolution Evidence Item)
NPC: Assistant Trevor
Location: Fuschia City
Dialogue: (this person also won't intiate the quest unless you have 2 Evolution Evidence items in your possession)
I was researching Pokemon from the Cinnabar Island and I discovered something interesting. There is evidence that Ditto once lived on Cinnabar Island as well as Eevee, and both carry some transformative properties unique to their lines. That makes me wonder what advantage Ditto has over its environment by changing to various Pokemon appearances. Would you help me with this area of research?
(yes or no choice) If yes:
(He gives you a level 1 Ditto)
I need you to train this Ditto to level 90 and take note of how it interacts with its environment. This is very important for my Eevee research but my personal time is limited so I can't train it myself.
(Train that same Ditto to level 90)
I see, so the Ditto was able to survive from its ability to transform. There is a Ditto Master in the Safari Zone I would also like you to speak to. I came here to meet him but he's too busy trying to find Chansey.
(Go to the first map of the Safari Zone)
NPC: Ditto master
Location: Safari Zone
Dialogue: (Only speaks to you if you have a Ditto on your team- I suppose this is like a gym leader you can only battle once)
So you have a Ditto.. LET'S BATTLE!!
(His Team has 2 level 90 Ditto)
You're pretty good with Ditto. And I see you were sent here by Assistant Trevor, when you see him again can you give this statue to him? Thanks!
(You recieve a Ditto Statue)
(Talk to Assistant Trevor again):
Oh good, you got the Ditto Statue for me! I suppose it had a difficult time when battling other Dittos too right? That's why I think Eevee gained the ability to evolve into Jolteon after they appeared here. It needed to have an advantage over Vaporeon so that it could survive, so it evolved into an element that had an advantage over its former evolution. My area of research is complete!
(You recieve another Evolution Evidence Item. He also takes the Ditto Statue from your inventory so it isn't there as junk)
Our research is nearly complete, but there are still two evolutions that we are investigating: Espeon and Umbreon. Visit Saffron, my fellow assistants are there.
NPC: Assistant Sam
Location: Saffron City
Dialogue: (this person also won't intiate the quest unless you have 3 Evolution Evidence items in your possession)
Did you know some Pokemon can evolve when happy? Why do you suppose that is? I guess I'm asking too many questions. I was studying Eevee evolutions and it was discovered later that Eevee could evolve into Espeon and Umberon when very happy. There was evidence that Espeon existed here in the wild at one point but they disappeared when humans settled the place. I would like help researching the curiosity that is Espeon. Will you help me?
(yes or no choice) if yes-
(You receive a level 1 Eevee)
Please take this Eevee and evolve it into Espeon. I would like to see what sort of changes this Eevee went through as it accompanied you.
(You evolve the Eevee into Espeon)
That Espeon looks wonderfully happy. Isn't it strange that they need humans to happiness evolve now? My research suggests that Eevee stopped happiness evolution because they were once scared of people. It would also be why they are no longer found in the wild here. May I ask for one more favor? Please take care of that Espeon. It was a research Eevee but it looks so happy that I don't want to hurt it by tearing it away from you.
(You recieve another Evolution Evidence Item)
Here's my Evolution Evidence. Please see our last researcher at Lavender Town.
NPC: Assistant Guss
Location: Lavender Town.
Dialogue: (this person also won't initiate the quest unless you have 4 Evolution Evidence items in your possession)
Eevee has adapted to so many environments, but there was one problem- they were all diurnal. It makes sense for an Eevee to adapt to the night life and become an Umbreon to fill in that niche. But, why does it only evolve when it is happy? My personal theory is that as the Eevee migrated across Kanto, only the happiest ones were able to survive because happiness can bring inner strength. Would you like to help me on my research?
(yes or no choice) If yes:
Eevee does not react to Moon Stones when evolving into Umbreon and I want to investigate why. In the Rock Tunnel there are Onix that often drop Moon Stone Shards as they burrow through the cave deposits. Can you go and obtain 10 Moon Stone Shards for me? I want all 10 at once, not in increments.
(Go to the Rock Tunnel and defeat Onix for Moon Stone Shards)
(Give the 10 Moon Stone Shards to Assistant Guss)
Thank you, I think I figured it out! Moon Stones and their Shards originated from eons worth of meteorites across Kanto. Eevee didn't adapt to this foreign object so it found an alternate evolution method! Eevee are remarkable Pokemon! But my research isn't over yet. Why does it need happiness to evolve? I have a horrible idea that I need you to research behind the scenes..
I want you to raise an Eevee to have 0 happiness and show it to me. Are you willing to do that?
(yes or no choice) If yes:
(You receive a level 1 Eevee)
Take this Eevee and make it as unhappy as possible. I want to see 0 happiness.
(You show the Eevee with 0 happiness)
Hmm this Eevee looks terrible. It doesn't even have the will to eat, poor thing! I see why Eevee needs to be happy- their abilities are dependent on their physical and mental conditions and happy Eevee are strong Eevee! I don't want the police to come after me for allowing Pokemon abuse so keep and and raise it. And don't tell anyone about that Eevee!
Thank you for your help, I think you have helped me complete my research.
(You recieve another Evolution Evidence Item)
Here's my Evolution Evidence Item. Take your evidence back to Researcher Evan, I have a feeling he's eagerly awaiting the research results.
(Go back to Researcher Evan)
Researcher Evan: So my hunch was correct! I think my research group now has enough evidence to verify that Eevee was a Pokemon that had adapted to survive the changing environments. I am going to present my findings to the Global Pokemon Conference in Hoenn next year, wish me luck! And thank you for your help, I shall credit you as part of the research.
