Nameless Dan Heng, Chrysos Heir who guards the Earth's Coreflame, steadies the world as it falls, and guides all life across the land to a new home beyond.
“That, to me, is the Permanence: to trailblaze into the future, endlessly and eternally.”
“I'd like to reintroduce myself before I answer them — I am the Guard of the Astral Express, your companion, Dan Heng the Nameless.”
