Anlath is a large, greed-filled beast of shadow, the spawn of Yaelatha Zelvass, a member of House Zelvass. Anlath is a tortured souls that wanders the halls of the Tomb of Zelvass seeking precious objects to hide in his mother's tomb. Due to the dangers of being made in shadow, Yaelatha cast a blessing on Anlath that made him impervious when wreathed in light. However, he was capable of moving quickly and striking with great power in the dark, making him an extremely powerful being.
In Iron 951, Anlath met the Peas in battle as they sought the Sigil of Zelvass, which Anlath had stolen away to his room. The Peas were able to defeat Anlath, but the strange, black blood he left slowly began to reform itself after his defeat, hinting at his continued survival.
In Iron 958, Seamus McHammerface spoke with Anlath to coerce him into helping with the rebellion against Sanaris as part of the Great Throne War. Due to a special spell, Seamus was able to communicate effectively, but the simple Anlath could not understand why he should fight against Sanaris, which he considered his home. Despite Seamus' best attempts, Anlath could not be persuaded to leave the tomb, despite the torture it caused him.
