"Rude of him."

Acid's potentially useful. Some things can't be killed with fire.

"Yes, very rude. He spoke loudly of his plans, very much air and no thought."

"Do you remember anything specific he said?"

"You buy anything? Rude, rude. He says he was going to the prison plane." 

"I see." Carceri, huh. Interesting. She looks over to her companion. "Elatra? Find anything?"

She brings over a combination of healing potions and acid vials.

"We'll take these."

"Of course, of course. I may also recommend?"

"Sure."

He points at the unlabeled vials which contain unidentified brown and grey sludge. 

"Instant army."

"Golems?"

He says something incomprehensible.

"Gehreleths," he...clarifies?

"Ah."

"No."

He grumbles again in that incomprehensible tongue.

"One hundred and fourty jinx," he offers.

Money.

And here are their potions.

And a little bit extra. "Thanks for the help."

He bows awkwardly, refraining from shaking her hand. Probably wise.

And then they can be off.

"I think all that's left is getting supplies, then."

"No more 'contacts'?"

"I think we've got enough information to be going on with."

"Oh?"

"We know he left on the Styx, we know he's probably going to Carceri. He used to have celestial allies but I don't think many of them will still be talking to him; fiends will be, but the only party of them in the area isn't going to the same place. His daughter is chasing him, and not in a friendly way; we may be able to link up with her. He may have contracted the adventuring party, but they don't sound like too much trouble. And again, lich. If they don't know, that might turn them against him."
