Starwhale

Region

Outer Waters

Its minions

star jellies

The Starwhale is a cosmic leviathan with constellations on its night-blue skin, huge crystal spines along its back, crystal horns and a glowing blowhole, with a star-core gem set in its crown. It is the boss of the Outer Waters and the toughest of the four. It takes its turn as the harbor boss south of the harbor, and captains can summon it to its lair near the harbor with an Outer Waters sigil. It swims a wide loop around its arena.

It slams its tail, roars down a shower of stars onto glowing spots around the boats, and rams up from below. Its biggest move is the dive: a whirlpool forms, then it breaches up through the boats, throwing captains into the air in a star shower, with a wave rolling out after it. Its star jellies, with five-pointed star bells, haul themselves up the hull by their tentacles; knock them off with your rod. It has weak points in pairs on its head, its flanks and its tail. When it surfaces and holds still, follow the glowing handholds up its flanks, between its horns, and drop a bomb onto the crown gem. Captains who help tame it in its lair have a chance to find the Celestial Crown.
