"Perhaps," Findekáno says, "there's a sense in which we actually haven't invented indoor plumbing; theirs is better."
"I don't think we'll find any textbooks on how to make Milliways, it's not like electricity." Sigh. "I'm pretty sure the other Ardas don't have magic."
"Should I -"
"Refrain from telling them about it or bringing it about that they know of it, and if you learn that they do, tell me. Don't do any in front of them. Don't answer questions or direct them to sources for answers on its capabilities. Default to not telling them things, unless you want those things weaponized against everyone you care about -"
"Yes, your majesty."
"Night. I will wake you before I leave for breakfast."
"..."
"Tell me good night."
"Good night, my lord." Pause. "Are you angry with me -"
"No."
"It would be understandable to be angry with me, I shared information that's caused you a lot of trouble and I keep having disloyal thoughts about it -"
"It would be very understandable but I'm not angry. Go to sleep."
"If this is a kindness to me," Findekáno says after a minute, "it - isn't, not unexplained - did you swear to them you wouldn't -"
"No. Might need to swear I haven't, they were really upset by that in particular. I was not under the impression I was doing you a favor. Good night."
