Immediately after entering the Subspace, Karsha commanded the system to take him to an area where he could freely traverse the starry sky while training his movement skills. The first level of the Lightning Phoenix Drive required him to create or open connectors within the core of his wing. These connectors would enable him to channel both lightning and wind energies for offence, movement, and even some form of defence.
The wing, however, remained a mystery to him. Despite his reliance on the system for his cultivation, its abilities to probe the nature of the wing were limited. This wing was far more complex and powerful than he had initially anticipated, revealing a gap in the system's knowledge about external entities.
