Thym

Thym, known in the old ages as Eris, is the sole remaining satellite of Izbucn.

Features
Thym is a frozen dwarf world that used to float adrift in the outer fringes of the Kuiper Belt, but due to the powerful gravity of Izbucn, the object was pulled out of its orbit and into an orbit around the ice giant. Izbucn had recently finished annihilating its previous largest moon, Triton, but Thym orbits far enough away to avoid orbital decay, at least for now. It is largely unexplored due to its proximity in the Kuiper Belt. No human has set foot on Thym, and the surface appears desolate and barren, even for a world of the Archangel system.
