Apparently the lower levels of the mines have been flooded so going any deeper seems impossible at the moment. So the group focuses their attention back on the high priest of the Devourer. Museo offers the group to take them to the audience chamber. When asked about the high priest's victims she tells them that none of the sea elves are really prisoners. Only traitors are supposed to be sacrificed. Mord Morden usually takes care of that.
Museo offers the group a potion to breathe underwater. Sadly it's of Sahaguin making it taste horrible. Also it affects Nimue like poison for some reason so the group has to drag her along while swimming below the surface. Museo guesses that's because it took the Devourer's help to make it.
Finally, the adventurers reach a hall underwater which is filled with an air bubble. Sadly the high priest isn't there, but Mord Morden certainly is. A greenish portal towers over a throne on which he awaits the arrival of the adventurers. Two assassins flank the door and some sea elves stand guard on the sides. A ritual circle glows ominously in the middle of the room.
Mord is curious about the high priest's reason for wanting Nimue dead. Also he admits having been paid by Aumersair, the fake mantle king, and mocks the heroes to fall into his trap that easily. Aumersair, as Thana knows, was the name of a famous noble family which had governed Scardale long ago.
Nimue drinks from a potion of divinity after entering a ritual circle which Mord may have wanted to use against the group. Her body shifts into a dark fey version which takes Mord aback. Kerrick displays the bone dagger which he has pilfered. He tries to arouse Mord's suspicions against Aumersair that he obviously harbors. Meanwhile, Nimue sabotages the portal destroying it and one of the blood wells at the side.
Lesser demons appear from the blood. In the place of the portal a shadowy image of the high priest appears threatening Nimue. Apparently he's a bit miffed about the loss the portal. Sadly he proves to be more than a ghost who can also attack people with his spectral harpoon. He also summons a demon in the summoning circle which Shiel engages.
He viciously mauls Shiel assisted by his lesser demons. Kerrick tries to convince/coerce the watching sea elves into switching allegiance to the group. The one which he convinces is summarily backstabbed by one of the assassins however.
Shiel uses his psionic powers to warp time around him in an effort to keep the demons close to him as attacking allies will be painful. Nimue hits the shadowy high priest with one of her mighties thunder spells and drives him into the remaining blood fountain destroying it.
The demon and assassins prove no match for the rest of the group which relies on Thana's powerful wards to stave off most of the dangerous wounds. Nimue reverts to her "normal" state, the wings have disappeared and left horrible wounds.
Will even Thana's healing powers be able to restore a semblance of (un)life to her? The potion of divinity certainly has wrought some weird changes on her.
