Coyote (Texas Ranger) is a deliberate echo, in Antiterra, of Coyote, the wyvern rider of the main line of the Mega Campaign.
Coyote takes many forms across the shared cosmos. He was lost as an active companion but reappears much later as Hundun. The full updated cross-gesta reincarnation chain is: Natalio → El Indio → Coyote / Coyote → Arian → the Elisteo → [successive figures] → Hundun (the reappearance of Coyote).
The Texas Ranger in Antiterra is a resonance of the archetype within the same shared world.
