Sewer Encounters
Sewer encounters for creatures encountered in the tunnels, drains, undercrofts, and collapsed cellars beneath a settlement. The pool is heavy on vermin, oozes, fungi, and outcasts driven down for cover.
Roll the Sewer Type Table first, then the matching creature table below.
Some results on the Special creature table route to the matching subtable for the specific creature.
See Type Tables for the wilderness terrain and other distinct environments.
