This troper was this trope during a LiveActionRPG based on Morrowind. She suddenly became the Telvanni Archmagister because the previous Archmagister and all Masters perished.

You're Telvani, isn't that how going up the ranks works?

This troper joined a campus club. At the first meeting, he was named treasurer because "the previous one transferred to another school and you're the only accounting major in the group."

The ''only'' reason that I, the vice president of my anime club, and my friend, our president, have our positions at all is because three years ago, out of the blue, the then-president decided to name two new people to the executive and picked us just to spite an arrogant jerk who'd been gunning for a position all year.
