ArmorQuest
ArmorQuest is an allegorical fantasy comic, written by Ben Avery (creator of The Hedge Knight, The Hedge Knight II: The Sworn Sword and The Oz/Wonderland Chronicles) and drawn by Sherwin Schwartzrock who, according to www.webcomics.cc, "is one of those rare artists who truly does deserve Spider-Man title adjectives appended to his name. Amazing. Spectacular. Sensational. Friendly neighborhood." (Source: http://webcomics.cc/2011/02/spotlight-on-armorquest)
The story centers around a young boy named Timothy who is entrusted with a sword which has special capabilites.
