Yx

Yx was a supermassive blackhole located at the center of the Andromeda galaxy. It was buried deep within the Xebula, a massive timefractured starfield approximately 10,000 lightyears across, filled with stellar remants such as white dwarf stars, neutron stars, and other black holes. Against all odds, a single planet maintained a stable orbit Yx, known as Yx α, completing an orbit around its 'star' once every 100,000 years.
