Atlantis can easily be summed up as a stoic. He keeps his cool even in the direst of situations and prefers to logically solve issues whenever possible. He is not fond of meandering interactions, finding it to be meaningless and tedious. If it is not concerning his interests or his duties as a knight, Atlas is slow to action and unmotivated.
Atlantis is loyal to the Crown and the kingdom but he does not follow the King blindly. If ever his opinion is sought on a matter, he never hesitates to voice it honestly and faithfully, even at the risk of crossing with the King or other high members of the court. There have been moments where he's inwardly disapproved of the King's actions which have remained as tiny seeds of doubt in him.
It would seem that such traits should work opposingly to his reputation and yet, he finds himself gaining the approval of the King even more - such to the point that the King indulges him, unprompted, on certain state affairs and entrusts him as a royal envoy regarding specific missions.
However, Atlas is a straightforward person who treats all he meets fairly without prejudice. He seeks to form opinions of them after personally interacting with them and is not influenced by the thoughts of others.
