Past adventures have been with a multi-class & multi-race party including a half-orc fighter, halfling rogue, human paladin, gnomish magic-user(?), etc.
This party was one of the first organized groups to venture into the outside world to report back to the Council. They made some important discoveries (see The Enclave), but much remains to be learned. Orcs, spiders, and undead were found, indicating that Outside is a dangerous place.
The two main settings for adventures are the Enclave environment, and exploration of the outside wilderness. However, underground adventuring could occur in the Dwarven Catacombs or in other locations Outside.
