Lore & Background

Ketheric Thorm was once a respected leader and a Paladin dedicated to Tyr, the God of Justice. His life changed irrevocably when he sought to save his daughter, Katra, who had died years before the Shadow Curse was cast. Refusing to accept her death, he turned away from divine justice and sought power from darker entities, specifically making a pact with Myrkul, the Lord of the Dead. This bargain transformed him into an undead entity sustained by dark magic. He seized control of Moonrise Towers, turning it into a fortress protected by magical wards and shadowy guardians. The Shadow Curse was enacted specifically to resurrect Katra using Shar's power, not to preserve Isobel. Today, Isobel survives as a living human at Last Light Inn in Act 2, where her own divine magic and the light of Selûne counteract the curse that blankets the surrounding lands. Despite his villainous actions, Ketheric remains a figure of profound tragedy. He believes that saving his daughter justifies any sin committed along the way. His story serves as a cautionary tale within the Forgotten Realms about the dangers of grief unchecked and the corruption of good intentions when fueled by forbidden power.

In Their Own Story

The great doors of Moonrise Towers groaned open, revealing a throne room bathed in cold, spectral light. Ketheric stood before the Soul Prism, his hands trembling not from fear, but from the weight of centuries of regret. The air smelled of ozone and old blood. He whispered to the empty space where his daughter's spirit lingered, promising that no god or hero would take her away again. Behind him, shadows lengthened into claws, ready to tear apart any intruder who dared challenge his devotion.
