Engineer Lekon:
You're back! Let's see here... Ah, you've brought quite a few Vulture's Golden Feathers. You must have succeeded in defeating Master Rider Valdstone, or have defeated a great many Vulture Riders or Elite Riders. Ha ha! This will put a dent in their plans. I'm delighted with your progress!
Here is the reward I promised you. I know it's not much compared to what you've gone through, but I hope it helps.
Say...you've got a real knack for this. Care to go back out and hunt some more?
"Sure."
"No, I've had enough."
