Whirlwind

"First, the Great Machine. Then, sky fell away. Whirlwind ripped away the past. All honor lost, all hope. Judgment not enough. Cannot keep Wolves from Kings, Scar from Winter. Fell to fighting. Fell to hate."

- Variks,the Loyal

The Whirlwind was an event that triggered the collapse of the Eliksni civilization, caused at least in part by the departure of the Traveler. Like humanity’s Golden Age, the Eliksni experienced significant advancement in technology under the Traveler. When it left, the Houses fell to fighting each other and many Houses were wiped out. The Whirlwind occurred before humanity's first contact with the Traveler.
