Just to be clear, does the concept of redemption doesn't exist in FR?
It does and I think @Tulkash1 has got it down pretty well. Minor disagreement on neutral but neutral has always been the hardest to pin down
In first edition D&D changing gods came with penalty of one experience level -- it was never clear if this was from the former god or some AO like god. Alignment change was free unless it was involuntary then it came an experience point cost. (say your DM decided that your decision to join the Zents is not Lawful Good). You also lost your 'alignment language' which no longer exists.
In the realms Elistraee concerns herself with the redemption of the drow and the church has secret enclaves dedicated to converting Lolth's faithful.
