Eridanus' black guardian had been hunting.
The encounter with the horse had troubled him - he could still feel his ribs giving way beneath its hooves. They had healed quite a while ago, he had been only a cub then, but he could still remember how it felt. The horse was the closest thing he'd ever seen to a monster - a boogeyman. It had looked like death, with hide stretched tight over its bones, and eerie eyes. And it had attempted to sicken a rat.
He had thought they'd irradicated it. All the sickness, the plague. But the scent, as he was walking through his home, was unmistakeable.
He followed his nose, horror bubbling in his stomach when he came across a fairly large section of plants. They fair reeked of the horse's sickness, and were twisted and mangled, looking dead despite smelling, still, of life.
He knew what he had to do, and he could only hope Rift wouldn't be too mad. His stomach roiled, and he stepped forward, lowering his head over the first plant as though to drink. Burning bile dripped from his mouth like blood and water, landing on the plants and burning them.
@Rift if ya want! :D
