The faith of Sebiya once held sway over the Blue Cliffs, but its time has long passed. A handful of adherents kept up the rites of the triune goddess in the cliffside abbey—until its vault collapsed, as if crushed by a colossal invisible finger.
Rumor says the faithful still haunt the remains of the cenobium. If so, they’ve let the steeple-light go dark, the one that once guided ships safely past the rocky shore. Trade has dwindled since, and a pall over the mist-shrouded ruin discourages anyone who’d restore the beacon… or delve the ruin for their own ends.
The Sebiyan Cenobium is the first of six interlocking zines in a system-neutral megazungeon. Each zine holds six areas of six locations apiece: 216 sites, woven into one enormous crawl. This edition is statted for Shadowdark characters of levels 3–5, and plays fine with anything OSR-shaped.
