As soon as the fire giant Surtr along with the other demigod realm beasts appeared in the Central city of Arcana world, the nine hidden clans and WAMO received the news and they acted quickly to resolve the situation.
Unlike Fenrir who keeps his power suppressed to make sure that no one detects his presence, the fire giant couldn't do the same way. And the fact that this incident is happening at the headquarters of Arcana World makes it easier for the hidden clans to travel.
Vesyrn also received the news but unlike the other clans, the Death clan lacked a supreme realm expert, well atleast publicly, and to keep it that way, he made a personal visit while leaving Pierre Garcia at the clan to protect it in his absence.
But, when he arrived at the location, he saw that the fire giant isn't in a rampage mode but is only guarding the dome-shaped barrier.
