"In my world, faerie realms have names. Lost Hope was one of them—well, Lost Hope was possibly one of them. I do not know if it's the name of the castle or the name of the realm itself, but it's important enough for that fae to identify himself as the master." There's a pause while Strange mulls it over, thinking of another way to describe it.

"It's like the carnival. The Ringmaster is, well, master of the carnival which is the name of her realm."

He doesn't go ahead into explaining other terms. Strange waits, watching Foster, and looking over the man for any point of clarification or spark of insight or any part that obviously confused him.
