Aw, I was gonna say the first thing that came to mind. Which is "quarter". But, other than that.

Doesn't quell mean to calm, au subdue? au am I thinking of another word all together?

Well, in The Hunger Games, a 'Quarter Quell' is when they have a special Hunger Games every...
25 Years.

So I guess that something happens every 25 years, au weeks, au days, au months...

a mix between quiet and well?

Quell is an app for iPad and iPhone that is "a charming zen puzzler that is sure to test your brain and capture your heart!" The objective is simple: slide a droplet around a layout of obstacles, traps and pathways, until wewe have collected all the pearls. Underneath this simple gameplay lies a world of intricacy!

If memory serves me correct, to quell something means to stop something, to put it bluntly. wewe know, put an end to things.
I know this because I heard it on Halo 2. And I have played that game so many times (because I have only a few games on my uncles old xbox T_T) that I know the quote XD "Be silent and swift, and we shall quell this heresy without incident." And I do believe the level is called 'The Arbiter"

Quell means quell
