Born from the intersection of two colliding galaxies, the Ethereal Starweaver emerged as a being capable of manipulating the very fabric of starlight. Through countless cosmic cycles, it learned to weave stellar energies into intricate patterns that could protect and guide others through the surreal realm. When Teddy's presence was discovered, the Starweaver naturally aligned with the Celestial Sentinels, recognizing the importance of preserving cosmic harmony.

The Ethereal Starweaver possesses the unique ability to gather and manipulate stellar energies, weaving them into protective barriers, bridges across void spaces, and guidance systems for other Sentinels. Its mastery over starlight allows it to create temporary constellations that serve as warning systems and communication networks throughout the surreal realm. The Starweaver's powers are strongest during celestial convergences, when the barriers between stars are thinnest.

As a master craftsman of stellar energies, the Ethereal Starweaver serves as both protector and wayfinder for the Celestial Sentinels, creating safe passages through dangerous territories and maintaining a vast network of stellar warning systems that help guard Teddy from the Neon Reapers' advances.
