Yeah, I've made a similar observation in the past about the Snowhawk Mage style- Snowhawk existed as a city in Arena, but only as a ruined fort in TES5. Naturally, people who were paying attention were intrigued and wanted to know about who these "Snowhawk Mages" actually were, what their story was, what happened to the city. If it, like Saberkeel is just a low-effort thing with no story, I think that they could do a lot better, honestly.

I think in lieu of that, personally, I'd take it as a Maormer style- those upsweeping, fin/shell/wave-like motifs in the design gel very well with other "Maormer" styles, in particular Pyandonean: https://eso.mmo-fashion.com/category/database/miscellaneous/armor-weapons/style/pyandonean/, but also Dreadsails and Syrabanic Marine styles to an extent.
