Drow

A very uncommonly found people in Yonder, they primarily exist within the Underdark. The drow are commonly organized into matriarchal tribal groups within the Underdark. There are many of these tribes though they are usually of two different alignments. Those that worship Lloth and those that worship Sehanine. The societies that worship Lloth are more lawful evil in their organization and engage in things like slavery and work closely with the duregar war leaders that are often the ones who raid the Overworld for their slaves.
The tribes that follow Sehanine often base their settlements around the rare Moon Pools that exist within the Underdark. These usually form the centers of their temples which can be found in the centers of their settlements and the light of which illuminates the settlements.
