Astral Dreadnought

Astral Dreadnoughts are monsters of immense power that reside in the Astral Sea. They are of uncertain origin, though some tales state that the Chained God, Tharizdun, created them to destroy the realms of the Gods in the hopes of gaining escape from his prison. They are one of the few threats in the Astral Sea that have the capability of snapping the silver thread that tethers mortal visitors to their living bodies.
