I originally made this black and silver unicorn stallion for someone else's mod, but I've decided to make him available for download separately after finding this in amongst some old dev files. He uses all new meshes and textures and can be found mooching around just outside Vilverin. He is free to take and ride, won't attack when you draw a weapon and won't wander off when dismounted. He's un-killable and will even pile into a fight alongside his rider.

To give him a name of your choosing, go into the console while the unicorn is in your view, click on him once to select (id should come up at the top of the screen), then type setactorfullname "name of unicorn" and hit enter.
