“Take them to an orphanage and leave them there with money for their upkeep. Except that is complicated in this case by the fact that you mentioned they are perhaps fugitives from Chelish justice; if they are we will hand them over.”

"I would not Call it Justice. If they are Enslaved, would you Hand them Over Anyway? Would you Hand me Over, merely for Being Undead, such being apparently Lawful to Kill There?"

No one on the run from justice thinks it’s justice. “Osirion may at its discretion extradite any free person of Osirion to Cheliax on Cheliax’s credible assurance that they committed a serious crime in Cheliax, unless they can plead under truth magic that they did not commit the alleged crime. If someone wanted to extradite a slave they would pursue civil action against the slave’s owner and seek to be awarded the slave in civil court.”

"It seems that the Incentives Here are for Me to Enslave Them to Protect them from the Putative Justice of Cheliax." 

Haria wiggles, in deep thought. "And Yet That does not seem to be in Accordance with My Friend Eriape's Final Request."

"What are the Requirements to Found an Orphanage?"

He has to look that one up. "Orphanages may be founded by any Lawful church, or the Church of Sarenrae, if the other orphanages they operate perform in aggregate in the top two thirds of orphanages in Osirion."

"Can one Earmark a Donation for Such, by Means of a Contribution to the Church of Abadar?"

"Yes, you may contribute to the Church of Abadar's orphanages, and you may if you choose contribute money they may use only to found a new orphanage."

"May one Thereby Purchase the Naming Rights to the Resulting Orphanage?"

"It depends on how large the donation."

"With your Help, I have now Realized how Urgent it is to Found the 'Lady Eriape Was Innocent' Orphanage. Thank you, Sir Guard. When you See me again, I may have Fewer Dependents."

Thaaaat's going to obviously get refused on the grounds that no one wants an orphanage named after a patron lich but he doesn't want to be the one to tell the thing this news.

Also, Cheliax, your insane Avistani undead, so vastly inferior to our sensible Garundi undead, are leaking again and apparently evacuating fugitives by Teleport.
