The original Pandaemonium artwork released during the lead in to Endwalker did not show a beard on Lahabrea. I originally wondered if the man in the center was Hesperos until I saw the red mask. I wonder if we're going to see some body swapping.

The character in the back appears to be wearing white robes, which is interesting in itself given that it seems reserved for individuals valued for their objectivity and judgement. Now the real question is what creatures from Greek mythology are affiliated with the various animals shown? Snakes are always interesting for their association with both Echidna and the Gorgons, and there might be a Kraken in there too.
