Though he grew up on occasional tales of Azeroth's past (particularly the First War), Arnius had little interest in adventuring for himself until early last year.
Arnius is mostly a solo adventurer, though he enjoys joining guildmates and others for the occasional instance adventure. Once in a while he'll join a battleground.
Arnius enjoys reading, exploring, and arcane magic.
Though he first visited Dalaran (at level 23) in March last year, Arnius hasn't set his [Hearthstone] there since he dropped it a few months later. He now uses teleport spells to reach the Alliance capitals, Dalaran, and Theramore, and he sets his hearthstone near places he's questing.
