"An underwater city? That sounds quite fascinating," Roxana replies. "My friends call me the Shadow Archer, and I come from quite a distance away, you would not know it."  She dismisses the thought with a wave of her hand. "I do think I have been imposing upon you for long enough, we should all be taking our leave I think."  She steps back a bit from the entrance, glancing at her companions. 

In her mind she thinks, 'Whatever this creature is, it seems truly vile and vindictive. But I'm not sure how dangerous it is or that we ought to confront it. It seems stronger in that small room, making it hesitant to come out. I think we leave her and move on.' 

"How exquisitely kind, Shadow Archer..." the sea elf smiles. "You and your friends, feel free to come visit me again whenever any of you need healing or rest. I'll be happy to offer shelter and assistance, albeit to a few at a time."

"Though I've chosen a life of isolation," Seyntillua slowly places her left hand over her heart "I'm not insensitive to the bonds between people. If any of you are in need, bring them to me, and you can count on me to do my best to free them from all pain."

Telepathic comments: "She's planning to kill anyone you bring her. And the thought of how much you'll suffer when you discover you've brought someone you care about to their end, like a lamb to the slaughter, gives her a perverse satisfaction."

[[ OOC: I'll wait a bit to allow anyone who wants to interact further... otherwise I'll consider the party 'silently accepting' Roxana's proposal and I'll narrate them taking their leave of Seyntillua. ]]

The party takes leave of Seyntillua and at this point remains to be decided whether to explore again and what ...

The only paths that the party has noticed but not yet explored are:
- In this level, in the Merrow room, the spiral staircase that goes up.
- In the upper level, in the spectral captain room, the corridors system to the north.

Roxana chats with Gaer as the group leaves. "I do wonder if something should be done with that Seyntillua. But it seemed almost like she wanted us to come in there to confront her. And no getting her out of there."  She shakes her head. "We should maybe talk to the Lords from Below about her to see what they think. They seem aware of her and have just let her be. Or perhaps they are afraid of her."  

With most of the place explored, she suggests the group head for the staircase and see where that leads.  The corridors in the upper level can be done after. 

Gaer shivers: "The gratuitous malevolence of her intentions is unsettling, to say the least." But then he tries to consider what his beloved has said. "Your clarity is always a great plus, though. Yes, Seyntillua obviously feels strong in her lair. But if we really decide to face her, maybe we could fight her from a distance, without entering. We can target her from the threshold. And maybe even from above, from the section of her room where the ceiling has collapsed. But it wouldn't cost us anything, in fact, to also consult with the Lords from Below."

Meanwhile, the staircase is quickly reached. Following the spiral staircase upward, the party discovers that the steps at some point emerge from the water (a sign that the height reached must be that of the upper level of the dungeon)—but they continue. Our heroes finally come to see the sky again, where a timid sun is doing its best to brighten a windy Ches morning. The spiral staircase has led them back to the surface, in the southwest corner of the ruins.

When the group emerges back outside, Roxana takes a moment to enjoy the bright windy day. "It is nice to see the sun for a bit. But we should probably head back and try the other passages before we bid a more permanent farewell to this place. Everyone ready to continue?"  She takes a moment to check in with the others, then heads back the way they had just come and retraces the path to the upper-level passages they had not yet explored. 

Gaer smiles: "With you? Sure, whenever you want!"

The others also seem fully willing to finish exploring these dungeons, which have already yielded loot and knowledge; so the party continues. Descending the spiral staircase again to the lowest level, it's easy to reach the Permanent Teleportation Circle room, go to the upper level, and, with a short swim, pass Eldath's shrine and reach the room with the Waterdeep banner, where Captain Stedd's spirit still stands guard.

Khelbluen and Stedd exchange surprised glances. Perhaps, after so long, neither expected to see the other again.

"Yes, Stedd, it's Khelbluen..." Mival explains to the spirit (since the construct cannot speak) "He joined us in seeking the truth about Lord Rassalantar..."

The conversation between the doppelganger hero and the ghostly guardian continues, and, once he learns that his Lord, though dead, at least had a descendant - and that said descendant is there, before his eyes - the undead guardian's disturbing form begins to slowly dissolve, his features relaxing in an expression of relief, and his eyes shining with a glimmer of hope mixed with pride.

With another restless spirit put to rest, the party can now turn to the northern section of the room, the only part of the dungeon that has not yet been explored. It appears to be a system of ordinary corridors, where the floor has not caved in and the water is at the usual depth of 2', allowing for walking. An initial east-west corridor then bends north at both ends (1? / 2?). At a glance, there appears to be no difference between the two routes.

Roxana points to the passage on the west. "Let's approach from that way. See what this last bit of this place might show us."  With the others, she moves forward. 

The passage on the west soon reaches a point where the party can either continue straight, north (then turn east), or go right, east (then turn north—unless our heroes want to go in circles).

For the moment, these featureless corridors seem empty, and only the splash of our heroes' lower legs in the water can be heard.
