If you mean the white dragon like being who looks like something out of Evangellion talk to it and if you have a Essence of growth give it one then go to the GrowthRPG tavern it'll be near the fireplace at the back wearing a maid outfit and comes with a bone lance you can reallocate it and trade weapons from the start too. I managed to find him in the cardboard dungeon and it's rather strong but be warned do not try changing it's form it messes it up so save it's character code before doing it
