I smell some Geth-like mental connection, as we've both managed to independently write characters who lost left arms and had them replaced with prosthetics.
Must be a shared memory! Can't explain it otherwise.
Astrid looks great; although the OP post does mention for humanity that Earth is a long-lost myth, and nobody really knows where humans come from - they just seem to be everywhere.
But feel free to post her in the Characters Tab as well, as she's approved.
