The Brood didn't care much about its members, especially if one of them put himself into trouble like Xedros or Syrook did. Attacking a Dragon would incur revenge only if it was a gratuitous and malicious act, and only if the Dragon died.
There was only one exception to the rule: Hatchlings.
Attacking a Dragon whelp was always punished by death. When the footage of the Awakened trying to kill Shargein spread like wildfire among the Brood, so did the Origin Flames among the ruins of their associates' secret labs.
One by one, those who had helped Garvi and Janya were captured and brought to the Blood Desert where Leegaain's interrogation techniques and Salaark's mind-reading abilities pulled out the names of more Awakened to add to the list.
In less than a day the entire conspiracy was exposed and uprooted but there was no telling if more were brewing. On top of that, with Shargein's identity exposed, now no one would attack while the Wyrmling was around.
