Redreaver
Redreaver was technically his second account, as his first account was forgotten and abandoned after a brief fling with the Incinerator Bot. He came back soon after as his current incarnation of Redreaver, and hasn't had another account since then.
Redreaver spent most of his time quest sitting, albeit doing it at lv 80 as a SC ranger. Getting the keepall wish, before quest-levelling (no active exping, just questing and levelling from exp gained on them) to SH, then sitting again at level 1.
Redreaver is a student in real life, and therefore he qsits often, which grants him time to spend studying amongst other things.
