"That sounds like what Asphodel used to be it before the River Phlegethon flooded it." Thanatos has very faint memories of that Asphodel, and he often wondered if he actually remembers it or if it's some imagined placed based off Elysium and the surface before it was snowed over. (Thanatos also questions if he remembers the surface without snow or has been confusing it with Elysium.)

"Does everyone end up there regardless of who they were in life?"
