The Cost of the Mask

Time knows well the horrifying power of the Fierce Deity's mask and the consequences that might come from using it. But when he and the other heroes are up against an enemy that they haven't got the strength to defeat alone, what choice will the Hero of Time make? Don the mask once more? Or leave the others to die? Based on LU and inspired by a fanart by Chromatic Magpie on Tumblr.
