Help with AoS and RPG hybrid

Im working on a AoS and RPG hybrid and i need suggestions
(i.e. Quests, Spells, Terrain, and ANYTHING u want)
But! The quests have to do with races vs the undead. And most of the stuff has to be centered around the fact that the elves have to kill the undead. The map is in the attachment
I WILL GIVE CREDIT IF YOU ADD STUFF AND I KEEP IT

Well just to point out, the terrain is jacked up. Basically nothing... You haven't even bothered to put indications where stuff should go, and what to do.
