Lack of Map ideas >_<

[VoRteX]

Hey everyone,
i have a small team of people working on an rpg map, we've been at it for about 2 weeks, we had an initial plan but its kinda turned to dust ._.
the maps terraining and spells is almost complete although our main idea is gone,
can anyone help us for ideas? (These are big ideas, unique ones that set our rpg apart from the rest)
e.g having about 10 classes and each class has a spell to transform into a different animal or something (just an example) xD

Thanks

PS: Yes, i know you guys must be sick of hearing about rpgs ^^
PPS: I can get some screens of some terrain if necessary.
