On the other hand we may have just allied with the local version of sewer rats/eldritch abominations.
No turning back now, even if we just allied with the "alliance of evil" or "thing that killed all those corpses". Fully embrace your new alliance... perhaps you may even be able to lead them as an army if you become prominent enough in their society.
But like the others said, pick up those weapons and head north. Perhaps into that entranceway that appears to be the "brood village"? We saw it earlier, just down that pathway.
If you can get a quest of some sorts, that would be ideal as well. Perhaps you may want to name yourself, as to have something to introduce rather than "amnesiac robot thing".
I nominate "Slash" as your name. Because "Sludge n' Slash" sounds like an awesome name for this duo, at least to me.
Or perhaps "Spectros"... have no idea where I got that name, though it rings a bell. Hmm...
