Inspired by [[Nuadha]]?

It seems pretty plausable, actually. They both have a similar right arm and they both have a similar Stomp attack.
Weren't the Gods the one who created the Avon Creatures? They could have based Bran on Nuadha.

I was thinking the guardians were more like experiments gone wrong and sent there to guard so they don't take up space in Falias. The successful ones were things like Daols.
