This is Styx- a magical horse adopt by  Hagen20 . Styx is like Dusk, in that they are less of an animal and more of a spiritual or magical being. These beings are chosen as almost demi-gods by old gods themselves, to serve their will down below and oversee their domains. Perhaps they once were mortal, but have transcended this since selection, or perhaps they were created by the gods for their service. Styx's domain is battle and warfare. They are a harbinger of war and strife, and often show future battlegrounds and appear to leaders of warring factions, sometimes bearing messages of their ultimate victory or defeat. Far from encouraging battles, Styx appears more as a warning of their coming, and often bears scars demonstrating the horrors to come. Styx also realises the necessity of some battles, but does not glory in unnecessary bloodshed. Their adornments may vary with the culture and time, and often resemble that of the more righteous side, should one exist for a given battle. Such side may even be aided in some way/ It is said unnecessary cruelties lose his favour, but mercies please him. There may be kindness, even in war. Styx has seen far too many bloody battles to glory in them but is aware of the brutal reality of the world, and does his task with stoic grace and an unwavering sense of duty.
