In theory. It's incredibly difficult. Gods in my world will resurrect people sometimes, if a priest petitions them to do it, that's much more common than a mortal pulling it off. There are ways to prevent it from working, too. Why?

I know a lot of dead people.

I might be powerful enough, but I've been unable to ever figure out healing magic. Everything else comes almost naturally to me but I can't get anywhere with healing. I expect elves might figure it out within a century if you put a lot of resources towards that. I heard Mandos does a lot of resurrections?

Of people he approves of, yes. He does not approve of any of the Noldor.

...Ah. I have no idea whether or not he'll be able to prevent resurrections once you figure it out, but he might. Sorry.

It's fine. I'd personally rather it not exist, but I'll follow up, people'd care.

...When this is all over and we have plane shift working, I can take you to my world and have you killed in a way that prevents it. If that's what you want.

Yes, I'd caught that that was the next plot point. 

I'm sorry your last moments will probably be wondering what's going to feature in the next simulation.

Anyways. My life story. I fled. I studied magic, and swordplay, and less socially acceptable skills. I stole to survive for years, easy to adapt that skillset for murder. I found the people who killed my sister and repaid them. I found who hired them and before they died they told me that they were just a middleman. I learned that Alfirin arranged it. I learned Alfirin was, supposedly, dead.

Nod.

About a year before that, twenty years before now, Alfirin was the power behind the throne of the Kalziran magocracy. She helped the magocracy form and overthrow the old government in the last desperate days of the war with Bael Turath, and in exchange for that she had a seat on the council and the ear of the archmage. A man named Nerikross was envious of her position - the council seats are reserved for masters of particular areas of magic, he was a necromancer and she held that seat so there was no other seat available to him. He convinced the rest of the council that she was too much of a threat and they took her by surprise and destroyed her safeguards and killed her. I think she planned it all.

Once I learned it was her I traveled to Kalzir. I wasn't thinking terribly clearly at the time, if she'd been around there's no way I could have killed her, but. I discovered she wasn't. I didn't know what to do with myself for a time, but about fifteen years ago I decided to learn as much about her as I possibly could. Figure out why she did it if nothing else.

Five years ago, I learned that another one of my half-sisters was alive and, apparently, the prisoner of the magocracy. I tried to track her down and free her, but didn't get anywhere for over a year. Alfirin came to me then, said we had interests in common. I hated her, I hated her so much but... I knew I wouldn't stand a chance. And... better to focus my efforts on saving the sister that was still alive than avenging the one who was dead.

Nod.

I agreed to work with her, she gave me a lead which took me to Sternhill. It's a Kalziran city, not huge but it's a real city, about a hundred thousand people. I followed leads there for about two and a half years, always one step behind her captors. Alfirin sent some more people my way - unwitting pawns of hers, mostly. Mostly she sent them to stir up trouble, I think. One of them was alright - Marius, he was an alchemist and an assassin and, despite that, a good person. And a friend. There was some other trouble in the city, seemed unrelated at first. A new sort of magic-user popping up, mostly destructive powers. People were afraid and the local guards kept escalating, and the conduits - that's what they were called - the conduits escalated back. We tried supporting the conduits at first but it just got so bad...

Anyways, in the middle of all that, I find out where they were keeping Istiell. And, I wasn't even thinking, I just went, and Marius and the others came with me and she was there but it was a trap. Nerikross was there himself, and two other council members, and some Knights, and a handful of other powerful mages.

All I was thinking about was getting Istiell to safety, I pushed her behind me and told Marius to take her and run. I told them to go to Alfirin. And then I went into the room alone and I fought and then I was here.

I see. Thank you; that was a lovely story.

They raise an eyebrow.

That's an adjective.

I think once the Enemy's dead I'm supposed to take my people to go stop the demons in your world. I will. If you were wondering.

The demons mostly aren't in my plane anymore, those were all destroyed, eventually. There are lots of them in the Abyss. The limiting factor on the evil they can cause is not their numbers but the availability of victims. Given that, any attempt to go into the Abyss and end their evil is counterproductive, please don't try.

What makes it counterproductive?

You and anyone you took with would be very available victims. 

No, I mean, can they be killed -

Yes. Most forms of summoning, killing them will just send them back to the Abyss. Killing them when they've been Called - a more permanent kind of summoning - or killing them in the Abyss will stick. But many of them are very powerful, and there are tens of millions of them, at least.

So, it takes a while. Fine.

Please, please don't. You would not be the first to try.

Look, something is going to happen such that suddenly I have to, that's how it works.

I'm sorry. I won't let that happen, if you try to lead your people into the Abyss I will not wait until it will stick to kill you.

It will be different from Angband. Angband apparently includes hallucinations that are no worse than if you had never been taken, apart from PTSD.
