Took place on March 11th, 2026. PCs were level 5.

Synopsis

SESSION SUMMARY

The party fought and defeated a pack of ghouls in the sewers using melee, spores, desiccate, and shooting stars. Examination revealed the undead were ancient, blind non-humans. A truth curse from a prior spell mishap forced honest thoughts aloud. Following the seeking star, they descended a dwarven-carved stair into an ancient blind cult's complex with murals depicting worship of a 'Holy One' and sleeper obelisk. Stone speak unveiled rituals, sacrifices, and unspoken names. Abandoned dorms and chapel led to a purified chamber with thresholds. Beyond darkness, they found the glowing Eidolon obelisk, slain monks, and the rogue dwarf architect channeling it. He revealed Eidolons as Kalak's soul shards for rebirth, planning to absorb power. Subdued non-lethally, but Lumi's rewind backfired, awakening it. A slate golem disintegrated the dwarf; Alistair intervened with prismatic sphere and portal escape. Back at guild, promoted to B-class amid Eidolon threat revelations.
