Possible idea for a Gentleman Caller child

[Teravala]

This might be kind of like wearing a hat on a hat, but how do we feel about the idea of a child of the GC who is a grandchild of Maeve? This would make them 1/4 fey, 1/4 vistani, and half fiend. To me, it seems like a POWERFUL lineage, deep ties to the land itself, and a deep well of supernatural abilities to draw upon. VR guide to the shadow fey talks about 1/4 fey, and It seems like Maeve isn't above taking a mortal for a lover.

It sounds perfectly fine to me. My only observation is that wasn't in the plans, since each Gaz was to have one child of the Caller, and the one for Gaz V was Chezna. It could still work, since III had no Child and IV had two, so I mention it only as a lead-in to discussing the remaining planned groups of domains.

The planned remaining Gaz:
VI - Liffe, Vechor, Nocturnal Sea (including minor islands)
VII - Sea of Sorrows, Blaustein, Ghastria, Dominia, Markovia
VIII - Souragne, Saragoss, Sri Raji, Wildlands
IX - G'Henna, Har'Akir, Sebua, Pharazia
X - Nidala, Avonleigh, Shadowborn Manor, Odiare
XI - Paridon, Timor, Vorostokov, Sanguinia
XII - Farelle, Rokushima Taiyoo, I'Cath, New Domain 1
XIII - Staunton Bluffs, New Domain 2, New Domain 3, Bluetspur

We know XIII would have been the Familiar, so Staunton Bluffs and Bluetspur don't have a Child.

Anything for the other sets of domains will probably need to be made de novo, since a lot of those domains were barely (if at all) touched on in earlier materials, and don't have as many convenient hooks laying around. Looking through Mistipedia, I only found a very small number of Vistani associated with any of those domains:

Madam Fayina - her tribe travels somewhere along the coast of the Sea of Sorrows (Children of the Night: Vampires)
Marda - her tribe travels in G'Henna (Circle of Darkness)
Valana - a raunie not referred to as Madam/Madame, she's in Souragne (Night of the Walking Dead)

That's such a better answer than I was hoping for. I didnt know the planned order of the rest of the gaz so I was just kind of spitballing something. I did know that III didnt have one, so I figured president had been set for one domain to have 2, but I also had forgotten they covered the SR in gaz V.

Thank you for the info, being able to copy pasta that into my DM notes is huge.
