Main article: Fergunakil, Fergunakil starships.

Blood comets are an outlawed Fergunakil construct enabling single or small groups of Fergunak to float freely in space in a bubble of water frozen to ice on the outside and kept liquid close to the core.

The devices have numerous uses in combat, even though they are classified as an emergency life-preserving method by the Fergunakil schools. It is important to note that the Fergunak classify eating landbound sentients, as well as one another, in the same way.
