Aux's Name

[Steel Speedster ♂]

As the Coppermind points out, Aux's original name, 12124, could be thought of as spelling "Aux" if you translate the numbers into letters. (1 = A, 21 = U, 24 = X.) But additionally, I noticed that 1 + 2 + 1 + 2 + 4 = 10 (Honor's number) and 1 x 2 x 1 x 2 x 4 = 16 (the "main" Cosmere number). I doubt this is a coincidence, (it's probably just an easter egg though), and I'm seriously impressed that Brandon fit all three of these layers together.

Nin’s spren appeared nearby, and Szeth’s spren reached out as if for help. The Herald’s spren shook its head. “How fitting, 12124. This is what happens when you give them too much power. Learn your lesson here, if you are ever allowed to speak oaths again. You have let yourself become an attendant to your human, an auxiliary to his will.”

That was when I knew for sure that 12124 was Aux. the fact that he using the word squire made me suspicious, but that word confirmed it.

I took that to also mean this is a skybreaker thing. I think that's how all skybreaker and spren relationships work.
