Xiao's distinctive forehead diamond holds a profound significance in his lore, far beyond being a mere aesthetic detail. It is widely understood within the world of Teyvat that this unique purple diamond is, in fact, the true and intrinsic source of his formidable Anemo powers.
The True Source of His Anemo Abilities
Unlike other characters who visibly display their Elemental Vision, the Vision typically seen on Xiao's person, often attached to his clothing, is considered by many to be a mere facade. Ancient texts and songs detailing the story of the five Yakshas, powerful adepti including Xiao, suggest that the actual wellspring of his elemental capabilities resides within the radiant diamond on his forehead.
This core belief indicates that his power is not granted by an external artifact, but is an inherent part of his being, manifesting through this prominent feature.
Distinguishing Xiao's Powers
To clarify the unique nature of Xiao's power manifestation:
| Feature | Forehead Diamond | Visible Vision (e.g., on belt/clothing) |
|---|---|---|
| Nature of Power | True source of Anemo abilities | Believed to be a fake or symbolic item |
| Significance | Integral to his existence as a Yaksha | External, non-functional representation |
| Lore Origin | Detailed in ancient tales of the five Yakshas | Common in-game display for other characters |
This distinction underscores Xiao's unique position among Vision-wielders, hinting at a deeper, more inherent connection to the elemental forces he commands, deeply rooted in his identity as the last active Yaksha.
