One morning , there was a problem at Sunstone Island. Hiccup saw Alvin, the destroyer

Then Dagger came and attacked the villagers. The villagers came together and raised an army against the dragons. Their life came to an end. They needed a strategy. They would call the invincible armada. So, Hiccup said "we will do this the easy way or the hard way!!!"

"What was that I could feel? What was that I could hear? What was that funny smell?", Alvin asked with a massive voice. Behind him, a volcano arose from the dragons breath. The old Sunstone  Island turned into smoking dust.
