Underblown

Brackhaven ordered the detonation of mana bombs spread throughout the Ork Underground. The runners had to move quickly to save as much of Seattle as they could with the help of every contact who would answer. What's worse, Humanis has been infested by Insect Spirits, who were using the mana surges to create rifts to their home plane. The runners managed to stop several detonations and banish the Hive Queen from this plane.
While they're efforts made the difference, much of the city was devastated, thousands of lives lost, and swarms insects entered the material plane before a massive mana void was triggered by an underground ritual site triggered as some... thing escaped its ancient bonds below.
It was bad, but it could have been worse... and worse is still to come.
