Maester Lucas looks excited. "Lord Edmure has won a great victory! With our help, the Lannisters can no longer threaten Riverrun, thank the gods!"
"Were there any losses in the battle?"
"What of Gregor Clegane, then? Captured? Or dead?"
"Be sure Lord Edmure knows of our sworn swords' role in his battle."
"None significant, my [lady/lord]." Maester Lucas smiles. "It was a rout. Lord Edmure took many hostages, including two squires of Lord Tywin's own blood!"
For a moment the Maester's smile fades. "Escaped. The one blot on a perfect victory. But he has fled back to Lord Tywin. His host is shattered."
"Open a cask of my best wine! We will have a celebration!"
