Why This One Works Fast

Tables that want a harsher expedition with route choices and moral pressure.
GMs looking for a higher-level one-shot that still fits one night cleanly.
Groups that enjoy negotiating with monsters as much as fighting them.

The Adventure

The hamlets bordering Blindwater Fen are losing their sight by inches. The locals call it sight rot: silver tears, clouded pupils, and eventually a darkness no prayer seems able to lift. Field healer Sister Maelin Voss has slowed the disease, but without heart-reed sap, marsh ash, and one ritual phrase held by Granny Nettle-Eye, the cure will fail within days.

The party enters a swamp where routes are political, not just physical. Old marker stones lie broken by baronial surveyors. Ghost marsh knights remember who let the land be cut open. The green hag at the fen's core is monstrous, but she is also guarding a deeper bloom that the outside world helped unleash.

Mire of the Sightless Bloom is a wilderness exploration one-shot for higher-tier groups who want navigation choices, eerie set pieces, and a finale where slaying the hag is only one of several credible endings.
