I find myself in the mood for stories in which Merlin is being abused, someone finds out and frees him of that abuse. It can be a good old fashioned Merlin serving a noble who beats him, or a family member, even Arthur or one of the knights being abusive. Can be an AU, slave fic or modern AU. Just as long as it has helpless/hurt Merlin, lots of comfort, and a happy ending with Merlin being rescued. As usual for me, Gen/friendship only but pre-slash is fine if it can read as gen.
