Where the river slows, something else begins to grow.

The Blighted Basin festers beneath a canopy of toxic bloom and cultivated rot. The Sisters of Blight have claimed the wetlands as a living ritual ground, nurturing anchor plants, draining corrupted soil, and guiding the Blooming Rot toward completion. This is not a dormant shrine. The ritual is active. Spores drift across the water, arrows fall from hidden perches, and every unpurified corpse feeds the growth.

As the characters push deeper into the basin, they navigate toxic vents, predatory flora, unstable terrain, and a cult that understands how to weaponize the land itself. Cleansing becomes as important as combat. Killing without purification strengthens the ritual. Delay allows the bloom to spread.

At the northern rise stands Ilythra, enthroned within a massive toxic bloom sustained by two cultivated abominations. The final confrontation is shaped by ritual pressure, anchor destruction, and environmental escalation. Whether the party dismantles the infrastructure of rot or rushes the fallen saint directly will determine what survives the basin.

Adventure Description

Ilythra, Fallen Saint of Pestilence is a compact, escalation-driven Saints of Ruin adventure built around environmental pressure, corpse purification, and ritual disruption.

This release emphasizes momentum over exploration, hard choices over safe outcomes, and lasting consequences recorded beyond the adventure itself.

What’s Inside

• A three-stage ritual countdown tied to purification and environmental triggers.
• Region-wide arrow volleys with clear timing and cover mechanics.
• Anchor plants that function as environmental mini-bosses.
• A shifting final confrontation shaped by player decisions.
• An open battlefield structure with seven keyed areas.

This release emphasizes tactical positioning, resource management, and consequence-driven play within a hazardous wetland ritual site.

Saints of Ruin is a collaborative 5E adventure line about fallen saints, the cults that sustain them, and the consequences of belief taken too far. Each release is a compact hunt built around an active ritual, a single location, and outcomes that carry forward beyond the adventure.

This adventure can be adapted to your own campaign, played as a one-shot, or be part of the Starlight Chronicles setting that connects everything made by Kelfecil's Tales.
