Guilty Horizon follows the story of Commander Elara Callisto and her Assistant Commander (and lover) Pyralis.
The story follows their relationship with guilt, regret, and blame. The writing contains several non-consensual scenes, and is an 18+ story due to the many adult scenes.
It takes place in the same universe/a universe inspired by
Warhound,
written by
yuriposting,
as well as
Steel Jaws Speak No Evil,
written by
VivisLaboratory/HateGrenade.
The story however, is standalone and does not require reading of these works. (It is HIGHLY recommended however, as they are very good, and in my opinion have leagues better writing.)
