Also a question. I'm thinking that as fun as playing a Choker could be, it sounds like a little stupid fighter might not be the best fit for the campaign. What I have in mind as alternative would require a fair amount of customization but could be extremely cool, a time demon. The build would use a (Fiend Folio) Filth Imp, reflavoring his Diabolical Stench to an AoE frozen in time effect, and then taking Conduit of the Lower Planes 3/ Sphere Warlock 1. All three sphere instances would go towards expert access to a custom Time Sphere. Ideally, the 1st level would be a Temporal Sense that would detect rifts in time and the use of time-based abilities. 3rd level would be Augury. 5th level would be Alter Fortune. And 7th level would be Wrack reflavored to be a single target frozen in time effect.
As for personality and history, I was thinking that his natural diabolical nature would have mellowed (and his powers weakened) by centuries spent among halflings, eating heartily and smoking their 'leaf'. Instead, he's just selfish and lazy. Only the destruction of the halfling hamlet, and their fields! in the apocalypse has motivated him to get off his duff.
Sound workable?
Hmm... I was looking forward to seeing your choker rolling 40s down the highway out of his Escalade, though.
How about if we combine the two, kind of? The choker's quickness ability is kind of a time effect. How about a fiendish choker, where the fiendish blood has acted to augment the normally modest temporal abilities of the choker into something more powerful? I have no problem with unique fiends, or even with someone playing one.
As written, fiends don't become warlocks, though.
Warlocks can be any non-Outsider.
Since chokers only have 3 racial hit dice, and are CR 2, I think I'd start you with 4 class levels. So you could be a 4th level Conduit. (Saying you're a fiendish choker would really just be fluff, and we'd use the normal choker's stats, and maybe give you fire resist 5 or something, and let you take fiendish feats and classes.) You'd have one bonus Fiend or Monstrous feat, and next level you'd get your Sphere at will.
And yeah, we can come up with a Time sphere, no problem. I think we should choose powers from the Time domain and a few good psionic powers that mess with time, like Time Hop and Mass Time Hop.
Sound good?
Edit: How about this for a Sphere?
Time SphereSpecial: Three times per day, you can activate any power from this Sphere as a swift or immediate action, regardless of its normal casting time. Also, you can terminate any effect you create from your Sphere prematurely as a Free action.

Time Hop, Mass
Time Regression
He could have a Hat of Disguise as an item, or take the Harmless Appearance fiendish feat (which would fit with the Imp theme) to blend in with the halflings. Or maybe they just got used to him.
