Krios (disambiguation)

The name Krios may refer to one of at least two planets:


 * Krios (Federation) - a member world of the United Federation of Planets
 * Krios (Klingon Empire) - a subject world of the Klingon Empire

Background
The planet Krios was first referenced in the TNG episode "The Mind's Eye", as a Klingon world where the Federation was allegedly arming a rebel faction (later revealed to be armed by Romulans). It was later referenced as a seemingly autonomous world in TNG episode "The Perfect Mate". The Kriosian history established in this latter episode was also referenced in the ENT episode "Precious Cargo".

While the canonical information does not make it clear whether or not these multiple references to "Krios" are meant to be to a single planet, the novel Articles of the Federation establishes a Krios as a Federation member world, and A Burning House, another novel by the same author, establishes a Krios under Klingon military rule. Though not definitively stated, it seems apparent the intent is to make these two distinct planets.
