Contact War

Preparations for the Contact War began when the Dyrajt detected the Maanen incident. Using the singulus gifted to them by the First, they apparently pre-empted Adam's orders and linked to Sirius early, initiating the assault and hoping to gain glory for themselves by defeating humanity.

This attack is usually considered separate from the Solarian Purge as it was not instigated by the First themselves, but rather caused by one of the Triad 'jumping the gun', so to speak.
