Brace yourselves, because I've just had another DL dream and I'm becoming concerned about how emotionally invested I am in this quest.
This one was about the Daughters.
It started with Mathilde overhearing a guardsman complaining about Ranald and suggesting someone goes after his "kin" to teach him a lesson. After interrogating/terrifying the man, Mathilde learned that there was an enchanted forest/hedgemaze, beyond which was where two elven craft goddesses lived in secret, and they were supposed to be Ranald's kin. Mathilde realised that the man had been told this via mental suggestion to lure Mathilde to the maze as a sort of invitation (because what are the odds some random nobody has the information she needs when she's in earshot?), so off she went.
As she approached the maze, she saw two girls, one with dark hair and blond highlights, and one with blond hair with dark highlights, run into to the maze and go off in different directions. To find her way through, she would have to find the girls—only there were hundreds of illusionary versions of them. Also tons of portals which zapped you around the map. Classic RPG puzzle dungeon stuff.
Mathilde noticed that the illusions of the light haired girl tended to cluster around the portals, but one was instead by herself staring at a flower, and that was the real sister. Upon finding her, the entire scene changed to underwater and the illusionary girls turned into manta rays—big, enthusiastic puppy-like manta rays who loved being stroked. Not only did you have to find the correct girl disguised as a manta ray (she was the largest one) but you had to turn her back—which involved feeding her red jellybeans. (Side note, I find it interesting that the blond one was Shallyan in nature by being entranced by the beauty of the flower, whilst the dark haired one was Ranaldian in nature by disguising herself, and only turned back when bribed with sweets).
Having found the two girls. Mathilde was invited to a family dinner at Ranald's and Shallya's modern kitchen apartment. Shallya was serving up some food whilst Ranald was fussing over the rice cooker, and all four plus Mathilde sat down to eat. The family had a fairly normal family conversation, which left Mathilde completely bewildered and with no idea of how to act (also, Ranald and Shallya were twice the size of Mathilde, and the daughters just a little taller, despite being about 12-ish). At one point the conversation turned to the Lady of Bretonnia, and Ranald went into a bit of a rant and even Shallya was frosty on the subject.
At the end of the meal, the Daughters improved Mathilde's enchanted robes and Ranald gifted her some books from our world—I couldn't see which ones, because you can't read text in dreams, but I'm fairly sure one was a Discworld book—and also showed her the cash shop where she could buy some cheat items, before sending her home.
