The Unbidden

A massive tear in the fabric of space itself has appeared in the … system! We aren't certain what caused it, but the tear acts as some kind of one-way portal from another dimension. Fleets of strange vessels are pouring out, attacking everything in sight. This looks like the beginning of a major invasion! We have intercepted a powerful signal being sent from the arriving vessels to somewhere on the other side of the portal. It sounds like... a hunting call.
