3 Skeleton Key

[Inner Self+AC] Far from any coast, a bare island rises from the sea—its lighthouse the only mark of life against endless water. Three people tend the light, bound by duty, isolation, & routine. The sea is their world, the beacon their purpose. Then, one evening, a derelict vessel drifts onto the reef. No signal. No crew. No sound—only movement across the deck. As the tide recedes, the truth becomes clear: the ship is alive with a seething mass of rats, thousands upon thousands, pouring over the rail & swarming toward the cliffs. There is nowhere to run. Only the tower, the light, & the long night ahead. Survive until dawn. Keep the beacon burning. The tide will rise again. Inspired by the short story "Three Skeleton Key" by French author Georges-Gustave Toudouze, and more specifically the radio dramas, often featuring Vincent Price. 2026-01-17: Now with Inner Self script by the inestimable LewdLeah (https://play.aidungeon.com/scenario/tsu1WMJXaaAZ/inner-self?share=true); Auto Cards enabled, remember to add names of important NPCs to Config Story Card Notes.
