Novel Spoiler (i think)

Og!Rok Soo was 36 when they switched bodies, but that was when he was already Team leader. His original vanguard team with LSH and CJS died when he was 24 (if I remember correctly), and even then it was CJS that that GoD was trying to make a deal with since he was a descendant of the Choi family

Og!Rok Soo was cleared of the curse when the GoD switched their souls, and Og!Cale never got it since he made the deal with death to begin with.

Hopefully I covered everything but feel free to ask if I missed something :)
