D&D 5e / OOZE TOMB OF THE OATHBREAKER / Otsuka RPG Day

"We have drunk from the lake for countless generations—its waters have quenched the thirst of our once mighty people! Poison, it is all poison now…" — Hypsynome, Centaur Chieftainess

A small band of reclusive, noble centaurs have seen their idyllic peace shattered, their holy water source befouled by unknown magic. When word of their plight reaches the party by chance, they heroically race against time to reach the troubled camp, encountering ravaged flora and desperate fauna along the way, as terrifying storms beset the region, drowning the land in unnatural substances. Agreeing to investigate the centaurs’ small, now almost completely corrupted lake, the adventurers discover a long buried evil has for some reason awakened—its wretched minions gathering in its wake. In this strange and gruesome adventure for fourth-level PCs, the party must navigate perilous wilds, face supernatural storms, and confront a sinister being whose dark past may hold the key to the stricken centaurs’ very salvation…or their final undoing.
