Webcomic / Sacred Pie
How to explain... Sacred Pie is a webcomic written by Phil Shaw, aka philbob, about three 20-somethings, Sid, Roonas, and Bob. Hanging out in their apartment one day, they're visited by a dying man called the Traveler. In his final breath, he gives them four items, a Tunic, a pair of Gloves, a pair of Boots, and a Medallion. Then his body disappears, and they take them, deciding to save the universe as he asked on the basis that there's nothing on TV anyways. The first thing they do is accidentally assassinate an alien Chancellor and try to escape. All that is just the first twelve or so pages, and it just gets crazier from there.
