Bosses

Region boss with no faction, in Exile's Hideout. Its hull is also the base of Ganden's Bastion ship.

The same ship as the Spear of Amnion, much tougher, in the Abyssal Warren Tombs.

Region boss with no faction, in Kassik's Drift (Deep Strata). Its hull is also the base of Tzhal's Bastion ship.

Queen of the Thermavores. Region boss in Nest Sanctum; Nestlings hatch from her eggs. Since Beta Patch 2, shooting a Thermavore angers it and its nearby packmates even while your reactor is cool.

Each faction's stronghold on the war maps: Ganden's on the Spear hull in Cloud Wake, Tzhal's on the Shield hull in The Gallows. A developer said killing the enemy Bastion is worth around 80,000 Merits, with an 'iirc'.
