Mhalir doesn't have the faintest idea if it's safe to Plane Shift in morph. He doesn't especially want to ask the cleric, that defeats the purpose of having a cleric who won't ask questions about the job. 

<Carissa? Do you think you can use Detect Magic to figure out whether a Plane Shift with someone in morph would be safe?> 

"Your stuff mostly doesn't show up to Detect Magic at all. Can you describe what morph, uh, does?"

Mhalir is pretty knowledgeable about morph, having done a great deal of his own research on it, and he's not especially hiding things like that from Carissa; he explains it for her. It involves a lot of planar manipulation; he's not sure if z-space corresponds one of to the other planes that wizards can access, or if it's undiscovered here. 

"I don't know. I'd expect it to have the same answer for Plane Shift as for Teleport and Dimension Door, those are also extraplanar manipulation. It definitely seems like it might cause problems."

Unhappy tail-wave. <I ought not risk it.> Unfortunately this means that the cleric is going to get a close look at a weird blue centaur-horse-alien. And that it'll be more inconvenient to exit Alloran's head without getting himself murdered; he'll have to sedate Alloran as usual and then leave a margin for him to wake up. Though, hmm, on reflection being asked to Plane Shift an unconscious blue alien isn't that much weirder than just the alien part, maybe they should just have Alloran sedated for all of it. In which case there's much less reason for him to go, but - he still needs to worry about Alloran's safety on the other side until he wakes up. 

It's inconvenient to ask the cleric of Sarenrae, who's back on the main ship. Probably Nirvana is pretty safe, if it's a Good god's domain and is meant for people to heal? And he can ask the cleric to get a local's attention and, hmm, maybe leave a letter with them?

...He's going to need Carissa's cooperation for this too, isn't he. 

<Carissa. My plan is to send Alloran to Nirvana alone, not in morph, but probably sedated so he does not murder me. Is it all right with you if I hop to your head from there and we begin our trial period, or would you prefer I figure out some other arrangement?> 

"That seems fine."

<Thank you.> 

And Mhalir paces. He informs his staff on the shuttle that he's made the decision to strand Alloran in one of the afterlife planes and take a wizard host instead, probably Carissa and he'll find another if this doesn't work out. Wizards are more powerful and useful than Alloran, and probably smarter than him too with the headbands, and also it would be preferable to have a host who doesn't hate him, and to be doing one fewer thing that would upset the Good gods, give them less incentive to mess with his plans. He sends a fairly polished message back to the ship too. Probably his people are going to be very confused, even concerned, but they're all carefully vetted for this exploratory mission, he expects all of them to be loyal to him. 

He writes a letter for the cleric to take to Nirvana. Has it printed onto actual paper and sealed. 

He waits for the time they agreed to meet to arrive. 

The cleric of Abadar shows up. He has some friends with him, but they don't enter the room.

Before even taking the cloaked shuttle down to meet him, Mhalir asks his medic to sedate Alloran, like they do for the pool, and bring Mhalir to Carissa. He slips out of Alloran's head as soon as the Andalite is mostly out. Carrying him like this will be irritating, but they do have some equipment for it, and he can ask Carissa if she has a spell too. 

She does. She has a spell for everything because she has terrifying patrons from another planet. 

Carissa is scared, but she's decided that doesn't make a lot of sense. Mhalir has really low expectations because his slave has been his enemy who hates him for the last several decades. Even if she is really really defiant sometimes she is going to be better at this than Alloran. And Mhalir - isn't Asmodean, though maybe he will be when he's had time to think about it, and while he's not he has his weird alien opinions about things instead which seem to include that it's entertaining if your slaves are opinionated. With that set aside a lot of her feelings just amount to - wishing she was safe, and she can't be, and this is probably safer than not-this, because the more useful she is the more lengths he'll go to if anything happens. (He might have her raised if she died? It feels arrogant and ridiculous to hope for this, but, like, there is an important way in which 'slave' is not an accurate gloss which is that she is actually quite valuable to him.)

And then there's the thing where she feels disloyal and confused all the time, which she doesn't really want anyone to see but - if he decides to be Asmodean he can probably help her with it, and if he doesn't he won't regard it as an important failing, so - it seems worth a try. 

Also she totally thought he had a Yeerk in her secretly anyway so it's kind of nice of him that he didn't.

Mhalir says nothing to address any of Carissa's thoughts, now isn't the time. One of Mhalir's staff hands Carissa the letter for the cleric to convey.

Rather than taking over at all, Mhalir just asks her politely to move sedated Alloran out of the invisible shuttle and over to the meeting-point once they've landed. 

She casts Reduce Person and then floats him on a disc behind her over to the meeting point. 

I don't mind you puppeting me, she thinks vaguely. If I can't handle this it won't be that I like being allowed to walk (she does like being allowed to walk), it'd be that it is making me more defiant rather than less so. It's just sort of hard to predict which way that will go.

"Hey." He takes the letter, frowning. "Does he - want to be in Nirvana."

"It's complicated. We paid for no questions."

"You should have paid a cleric of a different god if you wanted them to commit crimes for you."

"I am pretty confident you aren't committing any crimes." Winning smile - no he's Osirian, he's probably going to misinterpret it in one direction or another.

He interprets it by stepping back and folding his arms firmly across his chest. 

"Look, he's evil, we didn't want to kill him, we talked to a cleric of Sarenrae who thought they could maybe hold onto him for us."

He casts a truth spell. 

She lets it land, repeats herself. 

"Did you kidnap him."

"No!" Mhalir's not piloting right now.

"To your knowledge is the law after you."

"I want a refund for half our fee for not asking a lot of questions. It is possible that the Chelish military mistakenly thinks I deserted but I didn't and this guy didn't have anything to do with it."

"- fine." And he Plane Shifts.
