Bastion's "Skyltborg" is likely from Roegadyn language and means "shield-castle".

I've seen a few people trying to translate the term Skyltborg using real languages but the simpler and lore-connected solution is that it comes from the established Roegadyn language used for Sea Wolf names, with the elements *skylt* "shield" and *borg* "castle" both already listed in the dictionary on the official lore forum.

Why "shield castle" and not "castle shield"? I would **speculate** that the term is the original Roegadyn word for the fighting style rather than just the weapon. "Shield castle" could be a compound term more elegantly translated as "fortress" or "bastion".
