Beneath the Reeds (PF1)

From publisher blurb: Beneath the Reeds is an encounter stemming from a necromantic circle’s energies being renewed as a result of a fae ‘burial harmony’ taking place in the surrounding waters. Death may be inevitable, but undeath is only an unfortunate step away for the unprepared. Beneath the Reeds is a Q-Encounter, or Quick-Encounter, that can be run for a group of four to six players with 7th-level characters, ranging from medium to hard in difficulty.
