History
The Eleventh Inspector once implied that he assumed the Infinity Knights to be known on Earth in the 21st century, as he expressed surprise that a convention which he thought celebrated his own adventures (Chicago TARDIS 2011) wasn't named something else like "Convergence of Infinity Knight Fanatics".
