Anna, Licia, and I were talking with Marin late at night on the deck of her ship.
It had been a week since we joined her, so we were a little more comfortable talking about ourselves.
Her Gift, [Blue Revenge], allows her to summon any ship she has sunk, alongside its crew, as ghost familiars.
However, the crew doesn't have access to their Gifts, free will, or any semblance of conscience.
That aspect of her Gift is closer to Cassandra's ability to summon the spirit of the swords she has eaten than my ability to summon people from [Gacha Kingdom Building].
Aside from that, there's also an initial mana cost for summoning each of them and she needs to keep spending mana so that they don't disappear over time. The mana cost also increases the more ships she has summoned, meaning that if she goes all out she won't be able to fight for too long.
