Meet Loren, the intrepid kobold and main character of my last book, The Sun of Vallerane ^v^
Yes, she is missing and arm and it has been replaced by a weapon! Though it is not a mechanical arm that she can move at will, my world wouldn't be technologically advanced enough for that. But it has a mechanism that makes its blade spring to live if pressed against its victim, cutting through any armor on its path.
That makes Loren a very talented assassin!

Many thanks to  Jackrow for providing the sketch of this pic!
