The Eye of Tzo

Truly, in a universe of infinite scope, even the most bizarre and alien of events can occur.
For instance, here we have a binary system that collapsed in the most unusual way. The two stars aged over the course of billions of years until one, for reasons unknown, went supernova before its twin. While it never became a black hole, the resulting dwarf star was dense enough to attract the survivor. The red giant swallowed the husk whole, resulting in a parasitic phenomenon known by humans as a TZO, or Thorne-Żytkow Object.
It is not known how many of these exist, but due to the unusual circumstances in which they form, it is unlikely that there are many. To this day, only one has been found to exist.
Truly, this is such a universe.
