It won't contain your inner beast, nor will anyone feel safer around you while wearing it.
This mod takes the muzzle worn by Cerberus in World of Darkness and ports it to the Imperial Shadow Visor. Just like the original, beams of energy connected to metal plates hold the mask in place, and there's an optional version that hides the plates (but not the beams). The glow can also be turned off with the /visor command.
The mask is compatible with all characters. I've also included unique model assets for every character to make porting to other items easier, as the visor doesn't quite use all of them. As such, this is a rather large file. Also, be aware that the toggleable glow will only work if the item it's ported to has that functionality built in. Otherwise, it will always glow.
