"Reports are coming in of a major battle between Sikan forces and invading Chekut troops on the Sika homeworld. The Sikan administration has called for Galactic Alliance forces to intervene in what it calls 'an act of opportunist aggression,' and share prices have tumbled over fears that the invasion will draw more planets in the Expansion Region into the conflict."

The Chekut were a race of sentient beings that were native to the Cheku system.

The Chekut forces opportunistically invaded the planet Sika during the Second Galactic Civil War.
