going-down-to-spooky-town:

I like that if you play the TES games backwards the Dark Brotherhood’s method of introduction devolves

Skyrim: Kidnaps you in your sleep and brings you to an abandoned shack to test you by making you kill one of three people who may or may not be innocent

Oblivion: Breaks in to your hotel room and wakes you up to give you an invitation to join their murder club

Morrowind: stabs you in bed
