Osmo and his Orb of Wondrous Power
This 20-page fantasy role-playing supplement presents Osmo the Unbound, an evil sorcerer who returns from exile with the Orb of Wondrous Power, a crystal relic capable of twisting reality and creating monstrous forms. Designed as a climactic boss encounter for characters of levels 3–6, it includes Osmo’s backstory, abilities, and a unique lair chamber for use in a one-night finale, campaign ending, or side quest. The module is compatible with First Edition, Fifth Edition, and other OGL or OSR-style fantasy role-playing systems.
