I forgot to tell you. My fangame is like Pokemon Mystery Dungeon. Except there is no pokemon turning into a human. I'll tell you what I got so far:
~ As Celebi leave the Sage's Forest, Mew caught up to him/her and asked why he/she is leaving. Celebi mentioned he/she wanted to leave the forest to end the war. Mew then asked what will happen. Celebi said to tell the others he/she will will come back when he/she travel in time.
~ Meanwhile, Mewtwo; the bad guy of the game invaded the Summoner's village and kidnapped the newborn summoning pichu. However, because of Mewtwo's lack of interest, he abandoned the baby. ~
Let me explain:
There are two types of pichu: Normal and Summoning. I'll explain more about it later.
I don't know if Celebi should be a he or a she.
And Mewtwo is the bad pokemon.
