He was supposed to be her mission.

"No one summons Vespertine at dawn unless they have a death wish. Or someone is about to die."
Raised as a weapon by the most feared rebel leader in the kingdom, Vespertine Kerrigan has never been allowed to dream of freedom. Until an opportunity presents itself──a mission in the Capital.
