Many Questers were searching for an adventure, and Roy ended up having a charge to follow. Put two and two together, and you get this helping.
Roy was ordered to face a Wyrm, which was a Dragon of his realm. Sally wanted to see this Dragon, for she has been trying to obtain one as a pet for some time that it drove Wolfman insane. The Questers agreed to help Roy...and so did Marth, who chose to tag along.
The journey took the group to the Fire Emblem realm, where Marth and Roy were able to lead the expedition rather well. While they were ambushed by the local gremlins and goblins and the visiting ropes, it wasn't that bad of an ordeal.
The Wyrm was reached...but it was in a cave. The Questers hid while Sally drove it out. Roy's sword proved to be no match, for it was of the fire element...but Marth's sword worked just fine. So Roy used a stick on the ground for his attacks, but it wasn't even close to effective. Thanks to the team effort of the others, though, the Wyrm was defeated.
Once the Questers got back, Sally finally agreed to not have a dragon as a pet...she wanted something else. Wolf immediately left R&R to try to figure this out.
