Just started playing.  Aside from picking up quests in the wild,  is it possible to build some sort of quest hub (tavern, etc) inside my city that would allow me to find more quests for my champions?

I seem to hit a wall where all current quests/beasts on the board are too strong for me to face,  and I need to find alternate options for experience.

It looks like I can have a 25% chance for 1 experience point if I hang out in a city with the right buildings, but that's doesn't seem very effective...
