While Arcos is a stubborn dragon and oftentimes will make it known that he believes that something is not being done properly, he has the good sense of mind to let his bond help in the whole 'decision making' process. He can, at times, seem a little harsh... but then again, what dragon with such dark lineage isn't? At least he's intelligent, and usually possesses an even temper.
