Yes they are very powerful, and get access to S.

The following information was posted by Kristoffer O:

New hero:
Once and Future Queen. Reemerging Basalt Queen. Priest lvl4. Can get special unit events while in the sea. High MR and resistant to R'lyeh dream influence (insanity).

New units:
Sleeping Pillars. Unique event unit. Basically a living pillar of EA with high magic defence and dream resistance.

Underwater recruitables:
Unsleeping. Basically a non sacred mother guard with higher MR and dream resistance.
Merciful mother. More or less a mother of the deep with increased MR and dream resistance.
Forgiving father. More or less a mage of the deep with increased MR and dream resistance. W2S1+R

Returning into the sea is now something LA Atlantis will pursue, since it will give them access to mid tier mages of different paths. They are hopefully better suited to reclaim the dream-ridden seas.
