Hmmm maybe.... though it does seem a bit cliche to me, though for a base plot line it isn't such a bad idea
Maybe it's got a curse though and all who came to it will inevitably cause trouble and the innkeeper needs help on stopping this...

Also In order to prevent property damage in battles I'm going to have a sort of system where if a fight starts the people are transported to a sort of battle field that can fight in and go all out.

I need more ideas! PEOPLE WHO ARE INTERESTED! GIVE ME YOUR IDEAS!
