Mast is one of the members of Aegis squad alongside Helm and Anchor, serving as the Ark's naval force. A whimsical sort who fancies herself as a kind of privateer and treasure hunting adventurer, Mast's tendencies to kick back and drink cause no end of headaches for Helm. A good chunk of this behavior stems from how she chafes at the Admire's state of wasting away as a glorified party boat for the rich, wishing nothing more than to sail out on the open seas.
