The wyvern knight found a perfect, flat part of the road and released the log down onto the swarm of pursuers...
***KZZZZZZZZZZTT***
"...the log smashed into the first line of the pursuit group, and the pursuers ended in a huge pile of horses and men. That's how our venerable ancestor first developed tactical wyvern bombardment, still used in our army." The kids that were sitting around the elderly general all let a loud 'ooooh' of awe and admiration.
"Grandpa, grandpa!" One of the younger boys suddenly raised his hand.
"Yes, Londo?""Tell us how he developed strategical wyvern bombardment for Lord Yung!""Yeah!" One of the girls agreed.
"And then, and then, how he rescued that young maiden who then was his wife!" The elderly man laughed at the kids and then rubbed his chin.
"Hah, you little urchins... well, I guess you don't have to go to sleep yet... allright, it all begun when..."***KZZZZZZZZZZTT***...the log smashed into the first line of the pursuit group, and the pursuers ended in a huge pile of horribly mangled/crushed/smashed corpses. The snowy cloud have risen and the neighing and screams was clearly heard, but it was obvious that the pursuers were stopped once and for all.
