As Davos's being mixes with the sea foam on the deck the party takes a moment to consider what they have done. Taking orders from Estor doesn't feel good but Braz's resolve to gain the Ultros, the next tool of prophecy that can be used to end the rule of the titans, holds strong.
For all of the hate and petty grievances of the cities that the party has been involved in, the desire to see people as arbitrators of their destinies - rather than pawns in a game of 20 squares between the gods and their enemies - holds strong.
Metron had a different aim - holding the ghostly forms of those the Ultros had captured before.
A prison for souls for eternity.
Ab Aeterno.
