This is the part of The_Last_Tuatha_De_Danann quest where you're hunting for Flaithbertach's grandchildren.
1. Go to Caer Meguaidd and speak to the mayor for the location of the kids.
2. Ask the mayor "About Flaithbertach's grandchildren..."
3. Tell the mayor "I will save these poor children."
4. Tell the mayor "That will work. Do it."
5. Go to your Notes. Choose "Notes on Eriu". It will read "Note 1: You chose to kill Flaithbertach's grandchildren."
Notably, I just tried another conversation path:
"About..." -> "I will save..." -> "No, other children aren't the solution" -> "Forget what I said. We will follow your idea about using little slaves"
...and ended up with the correct Note 1: "You chose to save Flaithbertach's grandchildren. You instead sacrificed the lives of other, slave children."
So, if you're decisive about sacrificing the slaves, you get the wrong note. Whereas if you flip flop on the issue, you get the correct note.
