Radiant wasn't actually certain that a boss had spawned. They simply had a similar line of thinking and stationed their players all throughout the world to be on the lookout. In the end, players from Radiant discovered unusual movements from Conquering Clouds at the World Tree and immediately reported back.
When Radiant heard the news, they were quite excited! If the other side had already grouped up, it meant they were about to start attacking the boss. If they hurried over and snuck up on them, maybe they would be able to steal the boss?
Radiant formed two groups of players and rushed towards the World Tree. The Radiant players, who had discovered the unusual movements, saw Conquering Clouds shoo them away, confirming their suspicions: a wild boss had definitely spawned here.
"Force your way past them!"
Hearing that their players were being cleared from the field, Radiant's guild leader ordered the two groups of players under him to prepare to sweep Conquering Cloud in one go.
