I must find this fic!

Attention! I am looking for a very old fic. I forgot the author and the title, but I know it has to do with a robot crash landing in an Equestria of an alternate universe. The first chapter starts with the robot crash landing on to Equestria from space and tearing apart a bunch of Timberwolves. What follows is the robot escaping from the crater he was previously in and helping out a Changeling Princess. Equestria is ruled by different monarchs, and I think Twilight is missing an eye. Well, she comes in when an investigation party sent by the monarchs tries to find the robot in the crater. Twilight is with a stallion and they are old. So... yea. Does anyone know what I am talking about?

EDIT: I think the title started with "IGM:" and then had more words to it.
