1. They are bound until they recapture the land of D'Vore from the Empire, reinstating K'azz as it's ruler
2. They cannot die until that happens.
but...
3. If that happens, then the Vow is fulfilled.
4. Then K'azz will die, and all other Avowed released
So...If I'm the new emperor, I make a contract with K'azz. He names me the successor to him, and I give him possession of D'vore until his death. The instant K'azz signs the note, he gets the land, he dies, all the Avowed die (or start to age normally) and the Emperor regains the land. It would literally be an instant.
The problem with the T'lan Imass is they have to somehow exterminate an entire planet, and probably that includes several ascendant Jaghut they cannot access (Hood, Gothos, the Huntress). So it's doomed to fail.
But the CG goal is not impossible at all. They can fulfill their oath with a little clever contracting that hurts nobody.
