The mysterious Tree of Resonance stands as a testament to the strength of nature, surviving its bio-mechanical implants millennia ago and still standing strong four thousand years later. For such a location to remain at peace, it must have a guardian. The enigmatic Aztech bears a strange resemblance to the Gizoids of the Nocturnus Clan's creation, but what is the truth behind the connection between her and Emerl? And will she let Sonic remain in her tree?

A robotic filter is obviously needed for Aztech's voice, but she talks fairly organically. In terms of vocal references, Skye Bennett's Mythra from Xenoblade Chronicles 2 provides excellent reference for what Aztech is supposed to sound like.
