About Nocturnal Obsidian Diadem
Forged for a vampire queen, this diadem carries Constance’s finest work—dark metal shaped with impossible precision, set with blood-red rubies said to mirror her gaze. When Greg fell ill, Constance ended their craft forever. Only nine remain. Those who enter the Shadowed Sanctuary and brave the Labyrinth of the Lost Echoes may uncover one… if the maze allows it. Are you the one in nine? Model by qtbec. Game: https://www.roblox.com/games/13972817563/Shadowed-Sanctuary
