"Are you the one whom had saved my daughter from the terrible clutches of evil? The kingdom, my wife, and I are in your debt for this valiant and honorable deed. Without my dear princess, I don't believe I could have gone on any further with my duties, and nay would the villagers of this humble kingdom either... Thank heavens I naught need to think nor dream a nightmare of that anymore! With heroes like you, the world would be a better place. Please feel free to use any of the castle's facilities... Including the armory! Go forth! I command you to, friend."
"You are the boy who valiantly rescued our entire kingdom from the far reaches of the Devil's temptation… You are truly a saint among regular men and the entire world must have their arms outreached in full support of your heroism."
"Thank you for your kind words, sir."
"A knight, a fallen Knight, once told me, 'Man cannot sleep until he is dead. Then he can truly rest.' I believe this is completely true, son. Men only truly sleep once they have passed. Sleep then is just practice for the Big one. Completely biased I may be, as an old man, but I truly believe that."
"I understand why you'd believe that, sir."
"A knight of such splendor and gratitude of your personal grandness should have access to every single available nook and cranny in the entire Kingdom. My shop is free already, however I am sure you can find one to your tastes."
