"We're noticing coordinated efforts between Harbingers. It's a behavior we've not seen before. As you all know, certain classes of Harbingers sometimes work together, such as Brawlers working in pairs or Wyverns in flocks of exactly one dozen. However, we're starting to see the different classes experimenting with working together." General Bowman, the highest ranking officer over the entire Toronto Tower, paced at the front of the large hangar where every single soldier was assembled. "Over the years, Crawlers have made several attempts to climb the towers, but they can never reach high enough before exhausting themselves and falling to their deaths. We've been able to count on that fact to keep us safe. But..."

Bowman used a remote to turn on the huge monitor behind him, which played footage of Wyverns flying Crawlers up the sides of a tower. Every tower around the world was fitted with plasma guns that shot at Wyverns when they reached a certain height. Just before reaching that height, however, the Wyverns helped the Crawlers latch onto the tower's exterior, too close for the guns the reach, and then climbed the rest of the way to the top where the humans occupied. "That, men, is footage captured by a drone at the Sydney Tower in Australia. That tower is now gone."
