Where is Nikoe originally from? I think you mentioned she's a merchant, so what are her wares? And am I correct in assuming that she's a fan of...fish? :3
So it's kind of funny, I had no idea about the first one until I got to Lookout Landing, then I had a moment of galaxy brain
Nikoe is Robbie and Jerrin's kid, Granté's older sibling. When you finish Tarrey Town in BOTW, Granté shows up there and will sell you duplicates of any of the special outfit pieces you've found, so I thought it was quite fitting since I made Nikoe to be a fabric and clothing merchant!
Robbie's quite proud of his children but despairs a little that neither of them wanted to go into technology research (which is why he instantly gravitates to Josha, he finally has a kid to mentor, lol)
As for your last question....
....maybe 👀 yes
(The Zora is another OC - her name is Hantela and she works at the Seabed Inn, so they interact quite often whenever Nikoe is in town)
