   Summary

   Megatron captures the Autobots’ newly ascended Prime and takes him as conjunx bellum (war bride) to end the war. He expects defiance. Resentment. A fragile peace balanced on the edge of a blade.

   He doesn’t expect trust.
   He doesn’t expect love.
   And he definitely doesn’t expect the gods to take notice.
