Falmer and robots don't like me

After finally figureing out how to buy a house and then locating it, I went exploring more.

First I found a cave where a bunch of thieves were hiding out, made quick work of them, and then found the cam of the rebel faction. Then I wandered found a cave with a couple trolls living in it, they're not any more... and then I visited Shimmermist cave.

Right when I enter I notice that the place is really dark with a glowing blue mist everywhere, very creepy and there's a goblin-lizard thing on a ledge across from the entrance way. I try to sneak up on it and trigger a trap, causing a big metal claw to fall from the ceiling on me, taking off a third of my life. I try fighting the thing, called a falmer, and it's really tough, but I eventually kill it and get some rather heavy armor.

After killing several more of these (each time nearly dying), and some very nasty giant black centipede creatures, I come to the final room. In the room is another falmer, but this one has super powerful magic spells... and a giant robot! Some how this one can control a dwarven steampunk robot! After they kill me a dozen times I found a spot where I hide and snipe at the robot with arrows, and when it finally died I attacked the falmer wizard with full fire magic, chugging health and magic potions until it was dead.
