Achilleus is as brave as the largest dire and thinks himself as big as Fenrir. Being a toki, however, people seem to think that he likes to be babied, which is far from the truth. He is highly independent and territorial, and doesn't tolerate tresspassers of any kind. He doesn't back down from any challenge either, and he will do anything in his power in order to win. He absolutely hates losing, and he may throw a fit if things don't happen the way he wants them to. Loyal only to a selected few, once you enter his circle of trust you can be sure that you've got a friend for life.
