The Sentinel Frame is the frame the Stalker drones were issued from: a plated chassis whose standing order is to hold its Node's coordinate. It does not distinguish the operative from the breach. Where the Stalker pursues, the Sentinel waits.
Behaviour
It turns toward the nearest operative and stays where it stands. It is plated in front and open behind. After a short tell its clamps sweep out and drag whoever they catch out of the Node's ring, and a parry stops the sweep. From its dock it launches Stalkers of its own.
