Chariot

A roar in the gloom, a beat of a heart, and suddenly you're eye to eye with a putrid beast of terror and embers. Two raging eyes stare at you with a dazing violence, and another roar pierces from its drooling mouth with a most putrid smell.
A lush head of hair adorns its curved head, which itself is glowing faintly in the dark. A wheezing breath escapes the creature's large nostrils set within a massive nose.
Its curved head sits atop a hard, bony body. Chains are stuck within its flesh, but you don't wish to find out the probably horrifying specifics.
The creature darts toward you, its legs easily carry its diabolical body with a dreadful energy. A spiked tail slithers behind it, the crack of a whip can be heard with each of its swift movements.

Two cramped wings extend themselves fully. Visible bones, and blistering membranes stretch upward, and forcefully descend with a powerful gust. Unimpressed eyes still look at you, but only barely.
