Ok, done. Should be easier to read and has some additional information. For the already accepted characters, you may change them a bit if you so desire. 

[@Cyrania]The mage side would start with a mysterious cloaked stranger, who is obviously a mage, and a very powerful at that, offering them a job. That mage also hates Luminous Knights and himself has escaped from the life of a Servitor. In your character's case, it would be more of a little reunion. He already has freed a lot of mages, why not make your character one of those freed mages?

[@SPAssemble]Throughout the story, all characters will gain opportunities to learn new skill and/or improve old ones. They will also acquire new equipment. Pushing past natural limits require either mana of any kind and learning a specific technique, which all characters will encounter sooner or later, or specific body changes - like mechanical arms, yes. So in theory, you could acquire six mechanical arms which are far stronger than your normal ones, but nothing is ever for free when it comes to dwarves. Your character will need a lot of money. A LOT. Like the 0.01% amount of money. Of course, you can always settle for less.
