AethelLight Advanced Game Systems

AethelLight is a complete Unity game systems library extracted 

and generalized from Aethel's Light, a shipped 3D medieval 

fantasy RPG on Itch.io.

Every system is production-tested, Unity 6 compatible, and 

wired through a central C# event bus so packages never 

directly reference each other. Use one system, several, or 

the entire library without anything breaking.
