Crobat can tell there are things out in the darkness--huge things, looming and unpleasant, moving inaudibly among the dark waves. The smaller ones are about human-sized; the largest one is impossibly huge, a colossal horned and winged creature that has her head turned in the direction of their little party, watching but not (yet?) moving.

Avenger, though, only snorts. "Any Servant could wade into these waters and come through alive, if not entirely intact. But to leave these things be would only allow them to gather their strength and to grow. A curse is hardly a dead thing. It lives, it breathes, it consumes, it grows. And what, then, if it is allowed to do so unchecked?"
