The Dementia of Magic, you say? It's a comedic medieval webcomic that takes place in a universe created by a computer geek who's never read a page of Tolkien or played a round of D&D in his life. It primarily follows the lives of Matthew and Alexandria, two siblings who live in the Landis Kingdom in some sort of pseudo-medieval magic fantasy world.
The comic is meant to be read from the beginning. It's considerably serial, that is, plot-based and dependent on previous plots to advance the story. So you've gotta start from scratch and try to keep track of things. Sorry.
