I suspect you are the boss... the huge glowing circle kinda gives it away.
Fortunately the radiation didn't extend under the dome and inside waited a single man (possibly a dwemer): the Arbiter. Creator and enforcer of the Dwarves Law. He seemed pretty knowledgable about me too, about my affiliations, penchant for killing, stealing, and that I was from the future. With careful choices of responses I came close to convincing him to ending his law, showing that it was flawed since Metellus had outwitted him.
Alas, my greed got the better of me at the last prompt. Instead of saying "End your law and send me back to my time," I opted for "I'm not leaving empty handed."
His reply was simple: "Then you shall not leave at all."
The freak certainly enjoyed using lightning spells in combat but once he started failing his saving throws against my paralyzing bow he was screwed. I let him hobble around near the end, listening to him whimper about it being "Impossible". Then I took my sword and beheaded the f***er (you can tell he's an awesome bad guy to generate such hate!), and looted his neat helmet as my reward.
That explains his affinity with electricity.
Of course this means I had to potion my way back topside, where all the robots were torching everyone alive - again. I spotted Metellus running for the Lake house once more but this time decided to make a detour. Fortunately my amazing sneak skill let me slip past the angry robots and reach the burning body of the paranoid psycho to loot his piece of the Immaculate Dwarven Armor before shadowing back to the Lake house for take three.
