Yaxche

Yaxche is a huge monkey puzzle tree located deep in the mountain wilderness of Aztlan's Equatorial Ranges. Like all the other Scions of Heaven, it once had a portal to the Nether Realm that was closed off by the Gods at some point in its history, and the tree was grown from a twig from a tree in Heaven's Arcane Garden that was brought into the Physical Realm by Brahma almost 35,000 years before Book 1. It is by far the tallest and oldest tree on Aztlan, and all of its parts have magical properties. Weasel and his friends used some wood from the tree to forge the Celestial Bow, a short-lived Astral Artifact that allowed them to follow Tate to Xibalba. Yaxche was destroyed in the aftermath of Xibalba, but reborn when Neza planted a branch of the old tree to commemorate the founding of New Aztlan.
