Sorry, I'd have to advise against that. Every character, without exception, has been sheltered inside the city of Enn, which has no communication with other cities outside their own except for the Travellers. It's their own little bubble of existence. The technology does not exist in Enn to have a prosthetic arm outside of a hook or a stump. However, if you would like to obtain a working metal arm a bit later in the game, that is certainly possible.

Hmmm...this conundrum bears much thinking upon.
