The Rock is thought to be a remnant of [[Caliban]] itself that survived the [[Destruction of Caliban|destruction of the world]] at the end of the [[Horus Heresy]]. The remnant is built around the original Fortress-Monastery of the Dark Angels, which survived the destruction of the planet thanks to its shielding.{{Fn|7}} The Rock travels around the galaxy and visits most of the Dark Angels' recruiting worlds, and the [[Watchers in the Dark]] patrol its halls; an example of a Watcher is the small hooded being that follows Supreme Grand Master [[Azrael]] around, carrying the [[Lion Helm]]. The Rock is larger than any conventional class of [[Imperial]] warship and is capable of laying waste to entire fleets with its massive array of weaponry. The Rock is further protected by a constant escort of [[frigate]]s and squadrons of [[Thunderhawk]] Gunships.{{Fn|1a}} Beneath the surface of the rock lie vaults within which weapons of antiquity and terrible power are stored.{{Fn|13}}
