The Eternal Covenant is a relatively small Covenant successor state located in the Ikket'hai Cascade of the Siakar Expanse. As of 2565, it is under the leadership of the Jiralhanae warlord Targanus. The Eternal Covenant maintains tenuous alliances to several like-minded polities within Ikket'hai, and extracts tribute from a number of lesser worlds. While it seized most of its current territory with an initial, aggressive expansion phase, the Eternal Covenant appears to have lost its initial momentum and has grown passive since the tide turned against the Covenant loyalists in the wider Great Schism. Due to recurring skirmishes with other factions within the Ikket'hai Bloc as well as increasing encroachment by the neighboring Golden Compact and Chikri-Merkaa Conflux, a lack of significant alliances beyond Ikket'hai, as well as a domino effect resulting from the near-breakdown of supply chains to their worlds, it is suspected that both their resources and general morale have either run out or are at the risk of doing so in the immediate future.
