Dragonfire Adept can be any alignment, but it would take 6 levels to get the invocation, which is hardly a dip.
What about Beguiler from PHBII? Edit: Which is a full caster, so never mind.
So does anyone know of any non-source specific (so nothing like an Ebr Dragonmark), way for a LN non-full caster to get it? Be it a class dip, a feat or whatever?
I know, I was considering the PrC for the same campaign.
EDIT: Sorry, BoVD was the source.
