Grynewaht keeping an untranslated name

[Akonyl]

So, I know that with the naming conventions for Roes there's the "but sometimes the clans name themselves like the other clan" clause to keep lore names from being too restrictive for players, but I'm kind of curious how this applies to Grynewaht himself and why he isn't called "Green Guard" as a Hellsguard instead.

He certainly seems like the type who'd immediately snub the old language as soon as he had the chance, so I'm wondering if this was more a stylistic choice of thinking Grynewaht sounded like a better villain name, or if there might be a little more behind that? I can't really recall any other prominent Sea Wolf / Hellsguard figures who choose the alternate naming convention like this, Gosetsu would be the closest but afaik he's not actually either clan.

I'm pretty sure there are a few hellsguard with sea wolf names and reverse in the world or in quests. I can't think of any off the top of my head, but I do remember one hellsguard with an old name

Fyrgeiss (head of Amajinaa and sons/ syndicate member) is a Hellsguard. Lorebook says that he has an interest in Roegadyn history and has chosen to name himself and his sons in the old Roegadyn tongue.

Is it ever even stated where he (or Rhitatyn for that matter) hail from? They may belong to neither clan that we are familiar with.
