Void Kraken

A Void Kraken is a gargantuan, space-based xenos lifeform that is known to prey upon Imperial shipping. The physiology and nature of the Void Kraken are largely unknown, even to the most well-travelled explorers of the Koronus Expanse. This is doubtless the result of their rarity and difficulty to hunt and detect, but could also be that they represent more than a single species of void behemoth, several variations on the beast mistakenly considered a single race of creatures.
