Playing as the Dark Urge in changes much about the game and the story it follows, including adding one new character that is truly depraved.
That is Sceleritas Fel, the goblin butler who appears to the Dark Urge at night and encourages them to enact new atrocities.
Sceleritas is delightfully grotesque and bloodthirsty, taking immense joy in the Dark Urge's violence and expressing dismay at their self-control.
It is through this figure that players can learn much about their own backstory, butthe butler is remarkably tight-lipped about his own identity. He claims to serve the Dark Urge, but as the player has no memories, they have little to verify this until later in the game.
And even then, when the mystery of the Urge's nature is discovered, Sceleritas remains an enigma. But thanks to some theories made by fans and analysis of Forgotten Realms lore, it is possible to deduce just who — or what — this goblin is.
