Basically, similar to the Warlock's "Green Fire" quest, the end of this quest (which would take place in a phased version of Bloodmyst Isle) would give you a cosmetic makeover to your Ice spells, changing them from their normal color to blood red. This will also affect the appearance of your Water Elemental, and the Frost Mage's version of the Arch Mage's Prismatic Disc. You would, of course, be able to switch back to the normal ice color and vice versa.
