You fire more shots into the demons. They have nothing of value, in fact nothing at all, on their persons. You blow body parts off of them, and they do not respond.
The king is near death, and the Princess Margaret, eldest of the three, is also very badly injured. Nerene and Olivia are terrified but unharmed. The younger, Olivia, asks, "Who are you?" Nerene rather quietly says, "Thank you"--or at least you think she said that, as she barely made any noise.
This is the skill you have which cures damage:
1@1 Unlimited Damage Repair M+2@7 pray "God, heal my injuries, that I might continue this battle" for five minutes +3SM
I can see applying it to someone else and changing the reason as a new use of the skill. I am rewriting it as
1@1 Unlimited Damage Repair M+2@7 pray "God, heal (subject, possibly self) injuries, that (subject) might (do what needs to be done)" for five minutes +3SM
You still have to do it once for each of them.
You pray for the king, who begins recovering immediately and in a few minutes is fully recovered.
You pray for Margaret, but there is no change in her.
"Her heart is dying," Nerene says. "She loved Cathcart; she married him. Then she learned that she had wed a demon, and watched him die in the same moment."
"It was bad for us," Olivia says. "We were engaged to demons, by our own choice. But we weren't married."
"It may have saved your lives," the king says. "Dicalus and Eschevar wanted to marry you, so they would have legal claim to the throne. Had you married them, or had Cathcart survived, the demons would have had no use for us and would have killed us immediately so they could claim the throne.
"We owe you much, young man," the king says to you. "How do we repay you?"
