Xirix

The Xirix are multiple dark elf pre-Mending planeswalkers that work as assassins and mercenaries. Prior to the Mending, Xirix was a time traveler, and was able to meet their past selves should they go to the same time periods.

When the Mending occurred, Xirix lost their ability to time travel, leaving countless iterations of Xirix stranded across time and space.

During Reyhsia's travels through the Multiverse, she encountered multiple Xirix and helped several of them reunite.

The Arena
In 4568 AR, Reyhsia (possessed by Okus) invited a number of Xirix to The Arena to assist as guards during Okus's attack on the Seventh Circle Initiative. Not being aware of their true purpose in the scheme, one of the Xirix led Hannah Delcarlo-Nisita to the room where Karina Oblay was being held, allowing her to escape and alleviate some of the chaos left behind by Okus.

After this, a few Xirix stayed on the Arena, working under Sevid Fese at the Atlas Bakery.
