A quick concept artsy thing featuring Abeo and the fabled Black Stag.... Abeo is actually adult here, it's just that those deer are Megaloceroses and thus really big... Especially the Stag.
Few Continean souls have ever encountered the black stag, but almost everyone has heard of it. It is said to be a living shadow which only shows itself to hungry and lost souls of the forest. The stag entrances its victim with its otherworldly presence and then it drains their luck and hope, making them depressed and absent-minded.
Thus if someone seem sad or worried it has become a common phrase to say; "She just lost her son and now she's seen the black stag." or "What's the matter, it looks like you've seen the black stag!".
So, that's the black stag.
This dude may make an appearance in a coming storyboard
