It bothers me that Themis and Lahabrea are human-sized. They shouldn't be, they and Pandaemonium should be giants; it's not just correct, it's also much more interesting in terms of cutscene structure. But of course, I'm not tremendously surprised to see an Ancient story take the less interesting option.

Far more interesting to me in all this is learning that Mount Rokkon is going to be a journey alongside Hancock. That doesn't just confirm for sure that it's Hingan, but also confirms this is gonna be fun as hell, Hancock is an amazing pick for a character to have this sort of adventure alongside. I don't like him as a person, but he is solidly fun in a 'love to hate' way, and a capitalist with actual cultural curiosity (albeit mostly because it's something to profit from) is a genuinely solid angle for worldbuilding-centric content like a variant dungeon.
