ok so I might be drawing parallels where there are none but I'm rewatching c1 because of tlovm so.
when they're in the Feywild looking for Fenthras they find a hag's house in a giant tree that has a bit of a glow to it (in ep 62 Uninviting Waters). Pike and Scanlan go investigate on Vex's broom, and they roll shit, so we don't get much, but I'm thinking it might be Nana's house?
the episode transcript for the description is this :
MATT Okay. You don't pick up a lot of detail, but as you come up over the top, looking on the inside, it looks to be rather comfortable, surprisingly. It's a small home. There's a table, and there's a small hearth. There appears to be what looks to be a shelf of some kind, ramshackle, maybe, but still functional, with books pressed into it. You can see a number of small baskets hanging from the ceiling, containing various roots and other pieces of plant matter that are gathered and bundled together. You can see there is a fireplace by the hearth. There is also a series of drying animal carcasses hung in the corner that are all stripped, and they're being aired out in that space. You also see what looks to be a large chair that is facing the hearth, slightly away from you, and a small end table next to it that contains a little teacup and a little tea set.
TALIESIN What size person is the chair for?
MATT Actually, the chair is pretty large. It's tall. The tea set is small. And as you're making a look, you see one large crooked hand reach out from behind the chair with impossibly long fingers with hooked nails reach over. You can see what looks like dried wrappings hanging from parts of its wrist and elbow as it reaches over and wraps its gnarled fingers around this tiny teacup and pull it back behind the chair.
so I'm thinking either the hag/Morri just has a small tea set, or it's for a young Fearne or even for her second mouth on her stomach.
also the description loosely fits the one Matt gives of Nana's house in C3E45
MATT There, you're greeted by a low-lit, cozy entryway, a flat expanse at the base of where the split is. You can see it's decorated in knitted dolls, placed on little naturally warped tables. You can see animal skeletons that have been posed in dancing positions with each other that are placed up on little shelves and along the sides of the entryway. You can see alien-looking potted plants that seem to be taking root on their side of the room and guarding it fiercely. More of the staircases and rope bridges you can see begin to splinter off from here and lead higher and higher up through the tree.
[...]
The wide shoulders are thin. They come out like pointed, skeletal shoulders, the sleeves extending these long, thin arms. You see, around the top of the dress from where these shoulders are, they're obscured by a bunch of dark linen and chiffon that creates a mantle around it.
The tree's description isn't quite the same, but that part of the Feywild was weird(er than usual) because of Saundor, so it could have changed a lot between Vox Machina and Fearne bringing Bell's Hells to visit.
so we have this in C1E62 for the tree
MATT You see the tree, while it is thicker, it is not as high as the other trees. In fact, where there would be a top of a tree, it looks to be instead a tangled mass of branches that have been matted over and tied down to the top of where this tree ends.
and this in C3E45
MATT You step within the tree, and you can see the actual trunk of this structure, and you can see the actual trunk of this structure. This is probably the largest tree you've seen aside from the Sun Tree. It's comparable in its thickness. You can tell, about 30 feet up, it splits into two separate trunks that then wrap around each other in a corkscrew upward.
Now, none of those are 100% like the others, and I'm very likely reaching, but! I think it would be funny because it would make Nana Morri Artagan's ex :)
(as per C1E63: "She's many things, but she's not a hag. She's an ex.")
TLDR: I think Nana Morri might be the hag Vox Machina crossed paths with in the Feywild when they were looking for Fenthras which would make her Artagan's ex
