So the Geni Area is rather large. It's made up of 2 5x4 block areas. Because of the size, the spawn rate in the area can be poor. Especially if leucro's spawn in the area, causing the Geni's to stay in those rooms to kill the leucro rather than move to the room with the players. Additionally I think there are a lack of box dropping critters in the 300-700 range in a lot of the provinces around the game.

So the idea would be to add a Forest Djinn type creature to the area (Higher level Geni without having to resort to calling it an Elder Geni...) in the 400-600 range, perhaps with a ranged attack of some kind (so its not an exact copy of genis), to take over the SE Block, while the Geni's and Leucros are isloated to the NW block.
