The only thing I immediately don't like about Lyle is the bag of ball bearings which comes in the Burglar's Kit (and that's not your fault, it's the writers' fault for not only putting that in, but making it standard equipment for beginning Rogue PCs), not because I'm super-afraid of you using it to duplicate the effect of a Grease spell, but just because I think it's kind of setting-breaking for ball bearings to exist in a pre-industrial society. Could I persuade you to trade them for some other item of roughly similar (or slightly greater, if that's what it takes wink) GP value?
Also, since you're a halfling and I've already established that the town of Greenest has a high halfling population, would you feel okay about being a native? Up to you if you haven't actually taken up thieving yet (just having the natural tendency toward this skillset which halflings in general get), or if you've maybe returned to pastoral life temporarily as a way of lying low, waiting for the heat related to some former "job" of yours dies down...or, of course, some other backstory of your choice.)
@ gargoyleking - I thought I was being pretty generous offering that idea, which a lot of DMs would probably have thought of as Monty Haul cheese. But if you're okay with going Mage Armor in the short term, that works too. I'll try to make sure you don't suffer the missing spell slot for too long; part of why I'm going through with 1st-level play is my limited experience seeing wizards "in the field", so you temporarily playing a slightly more conventional wizard than you had in mind will at least be useful experience for me as a GM, and I will do my best to show my appreciation for your indulging me.
