The succubus trapped in the Dreaming Gulf is named Xinivrae (http://www.succubus.net/wiki/Xinivrae).  As far as I know, the 'character background' section on that link covers everything that's been revealed about her in official sources.  Malcanthet's artifact lash has the ability to inflict 'horrid wounds' that can't be healed without casting a<em>miracle</em>or<em>wish</em>on them first, so most likely, she's trapped at the bottom of the Dreaming Gulf due to being too badly-wounded to get out on her own.<br/><br/>Torahime is definitely going to want to be involved with the group going after Grimjaw, though she'll sit that one out if it looks like her talents will be put to better use elsewhere.<br/><br/>That said, I believe we also want to steal anything else that's particularly valuable that we might be able to find in Malcanthet's vaults, right?  Lining up a buyer for that treasure ahead of time would probably also be a good idea.  And once we learn more about her defenses and just what she has to steal, we can work on setting up whatever means we might use for transporting it away, as well.<br/><br/><div class="quoteheader"><div class="topslice_quote"><a href="https://elliquiy.com/forums/index.php?topic=283008.msg14218927#msg14218927">Quote from: TheGlyphstone on 19-06-2018, 18:15:42</a></div></div><blockquote class="bbc_standard_quote">Did the castle come with some sort of telepathic link between us?
