Dark Necropolitian Strongheart Halfling
Take Darkstalker and Lifesense. Small/Medium sized creatures emit 240ft bright illumination, 480ft dim illumination for you. I'm not sure about the rules for spotting the actual light, but it's pretty damn big, and creatures are not going to spot you 480ft away if you're hiding (in plain sight).
I plan on going Beguiler, lv1 dip in Mindbender, then figure it out from there. Taking Bloodline feats from Dragon magazine to get moar spells.
Have fun with 'The Corpse,' master of nabbing suprise rounds, setting up ambushes, and general trickery and stealth.
