I was playing this quest and i couldnt get to the artifacts so i killed the two people in the room, and they didnt get out... so i didnt get in trouble for the two murders. After i got the artifacts i left the house and right i as i came out, i saw a guard come after me. Well he told me to pay the 40 fine or go to jail and i figured i would just pay, and he brought me to Fort MoonMoth and i looked in my inventory and the artifacts were gone, those were the stolen artifacts still dont know how the guard saw me steal them in the house, but then i went back to the house to see if the artifacts were there and they werent... and i dont know were they went. If anyone knows where i can get them back, please tell me.... im stuck

They'll be in an evidence chest in the fort. otherwise you can just go find those artifacts in an actual dwemer ruin instead; you don't need the artifacts from ra'zhid in particular. And it doesn't matter if guards don't see you take anything, if you are arrested for anything they take any stolen goods you have. They are psychic or something.
