I am as world trees have ever been since the dawn of time. I watch, I understand. And I remember.
Nyralim, the Unbreaking, has limbs that cannot be shattered by any force - physical or magical. The great tree, one of the ancient Ring of Keozai, speaks to the Fae and mortals around it through visions, showing possible futures to those it deems worthy.
Nyralim has been a watcher of sorts since time began. Due to age (he existed since the dawn of time), he is highly respected among them and his words have much weight with the Court of Summer.
- The World Tree trope is common in media. Nyralim may be an homage to another famous sapient, benevolent and giant tree, the Great Deku Tree from the Legend of Zelda: Ocarina of Time. Both are likely inspired by Yggdrasil, the World Tree of Norse Mythology.
