Okay, so this is based on a scene from Epsilon ch7 p4, where Daryil imagines Jakob having fun with his boyfriend, Daxxon Skullbreaker. The image in the comic wasn't complete, and when I suggested cleaning it up for FA and Weasyl, Merlin responded by redrawing it completely.
Something I do regret a little in this is that Daxxon's eyes are obscured and the way they stared at each other was part of the charm in the original image. (Which is here: http://projectfuturecomic.com/epsilon.php?strip=07-04 )
So yes, after half a lifetime of denial, Jakob is firmly down the path of Daryil clan. He also looks nice with the longer hair, which is actually how he was supposed to have looked from day one.
Oh, and this is one of the few times you get to see his clan marking.
Lines by Merlin, colour and shinies by myself. Rated moderate for the gay.
