Are there any existing magical/artificial replacement arms written up?

So I lost my arm after shoving it into a cube and it getting cutoff… Honestly, I have been playing my character Wyn Wynn as a pretty straight forward Paladin of Lathander. I am new to the group I play with and the DM and players have given me credit and said I have been playing my character well and even like him as a character even if sometimes my character butts heads with one of the other characters. But now I want to stick out a bit and claim some glory for my own.

As I said I have just lost my arm, fun stuff truly but as luck would have it, we accepted a quest that if we clear out the tomb, we all get one wish. Now, assuming great Wyn Wynn the now one armed badass paladin lives, I was wondering: are there anything written about having an artificial limb or magical one in any of the official 5e D&D handbooks? I am hoping to wish myself a new arm that is magical or artificial. Not that my old Half-Elf arm wasn’t great, regrowing it just isn’t what I am looking for.
