"If Velgarth is another plane then we'll need to magically attune a targeting rod to it in order for me to Plane Shift there; if it's somewhere in this plane then I could get there by going to any other plane and then plane shifting back to the material plane with Velgarth as a destination in mind. I think the known other planets have magic work differently there but I don't know how differently or anything. 

I cannot in either case Plane Shift into the guy's room."

" - this is enough of a dick move that whether I'm comfortable with it kind of depends on what the guy's your enemy for, but it sounds like he was trying to travel to this plane and might need your cooperation, we could have you sit in the starplane while you cooperate with that."

"It didn't sound like he was at all close to getting a working spell, with or without my cooperation. Although, hmm – it's not necessary crazy to contact him and offer or at least give him warning that we're bringing him here because there's an urgent problem and we have to talk on neutral ground. I wouldn't feel bad about that - I mean, I'm not actually going to hurt him, I'd feel bad about doing that, but he's tried to have me assassinated before, or at least had a lot of contingency plans to do so and one of them went off by accident that he admitted to. He can't actually complain if 'neutral ground' means 'no magic to murder me with', and - honestly I think he'd understand, even if he doesn't like it." 

"That makes sense. - are you in fact not going to hurt him even if he's evil and definitely scheming against you, you probably want a plan for that -"

Sigh. "That's true. In that scenario, I can't even really send him back, if he's just going to start a war with Valdemar. I...don't know." It would hurt a lot to kill him, but that's probably really stupid. 

"If I were neutral good and had access to casual plane shifting I'd dump all my enemies on Nirvana. They can handle it."

" - we don't necessarily know for sure that they can!"

" - that's true do not actually bet the fate of any worlds on that without talking to anybody."

"I can't plane shift," Vanyel points out. "Can Fazil plane shift there? I guess it'd be worth, er, talking to someone there, if that's possible. Does magic work normally in the afterlives?" 

"Not fully and I think even less than usual in Nirvana's isle for people who they smuggled into Nirvana on grounds other than merit. I could probably take you there to talk to someone about whether there's a way for them to take custody of Leareth."

"That seems worth doing, then." His mind is still mulling on the question of how to get Leareth here in the first place. "Mahdi, can you do an involuntary teleport from a scroll - or we could test if I can help you power sixth-circle spells, maybe - and then do a plane shift once we have him? Or does that require you being where he is too?" 

"I can do the involuntary teleport from a scroll at maximum eight hundred feet of distance from him."

"Would the crystal ball let me move my viewpoint around and check for places within eight hundred feet where we can sneak in? I think that should be doable unless he's in some ridiculous underground bunker or something. Or, hmm, if I've seen his surroundings I might be able to try for it with normal Velgarth scrying, if I'm back in the same world, but he's more likely to shield that out... Can you teleport to a place you've seen in a scry if it's not his bedroom? Or would I have to somehow try to Gate us there? I guess I can check if I can get a Gate-destination just off looking in the crystal ball, if you know someone I can look for in a place I haven't been." 

"A normal crystal ball would not let you look around beyond immediate surroundings of the target, I don't know if this one is special in some way that gets around that. I can teleport to a place I've seen in a scry with a greater than typical but still objectively low chance of failing and ending up elsewhere."

"Is that a failure that's likely to result in serious harm, or just in me having to refill your teleport so you can try again?" 

"About one in ten chance it'll land us nearby but off target and one in ten it'll land us in a visually or magically similar location elsewhere in range. And about one in thirty that it'll injure everyone involved in the course of landing us nearby or in a similar area. Not lethally injure us, though you don't want to do dubious teleports with random civilians."

"Nearby but off target is probably fine. Hmm. I can hide us with an illusion and shields, but they might in themselves be detectable to a mage, or to magical wards. Your world's magic might not be, though - are there any spells or artifacts that make a person invisible, or undetectable to magic and mindreading?" 

"Yeah. Invisibility's easy, second circle, and nondetection is third."

"All right, we should do those, then. And plan on being fast, once we're there." 

Yfandes is still watching Leareth (it's very boring). :All right, I'm going to try moving my viewpoint to the next room:

Can she? 

No. 

:Aww. All right, I don't really know what to do, except have Vanyel try our kind of scrying from Velgarth, but it's probably shielded. Does your world have any other kinds of spell for locating people?: 

"Lots of kinds. The thing you want is probably clairvoyance, it's a moving scrying sensor, but it does not work across planes. Most things don't work across planes."

"We could scry the guy Leareth was talking to earlier and watch his surroundings? And keep doing that with additional people if he talks to any, though eventually we're going to run the poor ball down..."

:...Permanently? That seems bad. Or does it refill later?:
