Festival of Dancing Dangers standard sized d20

No one knows why, and few dared to investigate, the day the dragons met. The villagers looked up in horror to find two dragons flying above; one red and one blue. They thought they would destroy the town, but soon came to realize the two great beasts were virtually unaware of the ground folk below. These ancient behemoths had one sole focus; each other. For hours they circled each other in a mesmerizing dance of wings and fire. Never did they fires injure nor their talons tear the other. They continued to the awe of those below until the sun set. Then… without acknowledgment or warning, they flew their separate ways. The villagers pondered what it was they had just witnessed and thanked the Gods that was the end of it. Little did they know it had only just begun, for the dragons returned a year later. The same day, the same dance, the same parting. It continued this way to the point that a celebration was planned, the Festival of Dancing Dangers. The dragons and the festival carry on
