- You passively scan a small Rock station that is next to the beacon. However they must not have appreciated your curiosity. A Rock ship pulls away from the station and you register an incoming teleporter signal as well!
- You find a Rock ship docked with a damaged Mantis fighter. Before you have a chance to hail them, the ship moves in to attack you and you register teleporter symbols from the disabled ship. They're using Mantis tech to board you!
