Raven
Alright, I've decided to go with my initial idea (after reading about the inclusion of the Eberron races

) and make a changeling cleric or rogue/cleric, since the doppelganger is not going to join us.
I took one liberty in picking the Able Learner feat (as described above), which has Prerequisite: Human or Doppelganger, but given that changelings are the descendants of humans and doppelgangers, I suppose it's fine for them as well (and they really have the adaptability theme going for them as much as their ancestor races

). Anyways, if that's not fine with you, I can swap it out for Combat Expertise, of course.
So, unless there are any objections... all I need to do now is to decide between one of the two, while writing down the history...

Background: Raven had left her clan many years ago. The lure of the big wide world out there was just too strong to resist, and there was little for her to do in her home. She traveled around the countryside, often staying in the larger cities for weeks or even months, before getting on the road again. Raven needed supplies and money for her travels and the cities were the easiest place to get those... often for free, though occasionally this led to a rather hasty departure. The young changeling was always strangely fascinated by locks, especially closed ones and the interesting content behind them. This curiosity often got her into trouble, but it also gave her practice in all sorts of useful skills of the trade... and the supplies and money to finance her travels.
The latest place Raven traveled to is a city called Cauldron, located inside the mouth of a dormant volcano, the name appeared quite striking. Like all cities, Cauldron has a lot of locked doors, too. During the first week in Cauldron, Raven learned of a talented locksmith called Darius, who had made the city his home. Figuring, that his house would be a great challenge for her still developing skills, Raven set out to find out what was hidden behind his house's locks.
When she had made it inside, Raven was completely surpised by Darius who had noticed her entrance, and as she was just about to turn around and dash out, he called out to her and asked her to wait, and even though her reason was all against it, something made her stay. As it turned out, Darius was actually quite intrigued by her exploits. He asked her a few questions about the reason for her intrusion, and seemed to be pleased to hear, that she only wanted to know if she could get inside. As a follower of Dalt, Darius had pledged his life towards building locks and locking mechanisms, but there are also the followers of Dalt, who are meant to figure out and open these locks. When he told her about this, Raven instantly knew what her life would be like, what this inner voice was, which always urged her forward and stirred up her curiosity. She decided to stay a little longer and listen to his teachings...
