Here's some suggestions my love! And some plots to go along with it ^^
Canines
How about a little map with three packs? All of them have a different view on a religion, which is the Greek's religion. Zeus as the king of the gods, Hera, and etc. ^^ This can be a semi-realistic, to realistic roleplay, since of course... no one even knows if wolves do have a religion! Plus, it'd be a different idea ^^
Another idea that I have for you, if a virus. What if, it's almost like a zombie type virus? (This is inspired by World war Z ; Amazing movie) that a strange wolf appears in the territory of one of the packs. The creature could infect one of the wolves, and then die. This is how the virus is, once bitten, you become insane, since your brain is decaying, and then you die within a 24 hour period. The virus starts to spread, and the wolves try their bests to control it so that the virus completely stops spreading. ^^
I can do more if you want my love! I got tons xD
