Void Whales

A Void Whale is a gargantuan alien animal originally born in the currents of the Immaterium that also exists and “swims” through the vacuum of the open void in realspace. Nearly twelve thousand Terran kilometres long, these Warp-spawned entities are so large that their bodies both without and within become home to their own ecosystems made up of various other insidious creatures. Void Whales tend to swim across the blackness of space, and are also capable of navigating the unnatural tides of the Warp. In 877.M41, a hideously mutated Void Whale emerged from the Warp and was destroyed by a team of Space Wolves led by the Wolf Lord Engir Krakendoom. They landed on the Void Whale and fought their way through the vampiric bipedal creatures called Remora that called it home.
