The Sha'lythe Sect, commonly referred to as the "Time Guardians", are a large group of (originally sixty) warriors recruited by the Living Stars to aid them in protecting the fabric of time from temporal threats. These recruits were lost souls until called upon by the stars to do their duty to the multiverse. Each Time Guardians is given an elemental power to permanently wield should they have to fight, and a tool to channel their power with.
The living stars have vanished from their realm and have not communicated with any Time Guardians for some time now. As a result, most of them are just wandering around, confused and without purpose once more.
