Well, if you wanna know more about the Hylanders, they're a predominantly warrior society with hunter gatherers. They have a culture wielding large weapons due to the size of wildlife in the region they call home. They did not always use such large weapons, before, they used spears too being a hunter society, but a madman at the time began using large blades and hammers, and with how quickly they took down prey, they caught on. Though the advent of this was well before Hyrule's time.

Today, they accept Hylians who wish to learn their ways, and out of respect, Hyrule does not interfere in the area, with there being an ambassador from the region to represent them. Their traditions that might be of interest to you is their hunting festivals, feats of strength, and a warrior's pilgrimage to Snowcap Peaks, where they must bring back a yeti's pelt. The pilgrimage though is so dangerous it's not actively practiced anymore, but anyone who feels they are strong enough may attempt it. I will go on to say that's a pretty difficult feat, but as a Hylander, it may be of interest to you when the RP goes to Snowcap.

I'll probably have a discord up in the weekend, my free time had been preoccupied with FF16.
