The Trih Xeem

When the Pfhor realized they had lost, they activated the trih xeem, the "early nova." This Jjaro-derived weapon forced Lh'owon's sun into premature collapse. A scorched-earth tactic: if they couldn't control Lh'owon, no one would have it.

But something went wrong. Something far worse than a supernova. The sensors of the Pfhor fleet registered impossible readings, as if the universe had forgotten its own rules. A W'rkncacnter, one of the ancient beings of pure chaos imprisoned by the Jjaro within the star's gravity well for millennia, was now free.

In the final Marathon Infinity timeline, Durandal, who has merged with Thoth, activates Farcast station to contain the supernova and, with it, the W'rkncacnter.
