There are three basic views of the relics:
The Kalesians try to control relics and their wielders. If they can't be controlled, they're either used for breeding if possible or executed and their relic confiscated.
The people of the Fifth Dynasty set themselves up as false gods. Either an evoker joins in on that as a subordinate, or they are executed. What the Dynasty does with the relic afterwards is unclear.
The church and knights of Idris consider Relics and Evokers to be evil. They generally feel that the only good evoker is a dead evoker. Classic absolutist blind faith church, really.

The people elsewhere (at least in the environs of Othea are essentially forced to choose between these three options or to try to forge their own way, which can be hard considering three powerful factions make a mess of spiny weeds to wade through.
