Four generations of defence, read in the order the sky met them. Each one is a different answer to the same problem — what is the dragon looking at — and the older generations have never been retired, because a swamp still contains the creatures that made them necessary.
Epoch 1
The Signature Flame
1991–presentSignature Scales, a Norton Flame, Shield Wings and Vault Claws
The founding generation, and it works by recognition: the dragon carries the shape of every beast it has met and burns the shape again. Coverage was enormous and confidence was total, and both were the problem — a creature the dragon has never seen is not a threat, as far as this generation is able to conclude.
Behaviour · Patient, proprietary and slow to notice anything new: the generation that taught the sky how to burn, and how easily a burned sky trusts itself.

Epoch 2
The Fortress Breath
2000–2015Crypto Scales, a Tunnel Flame, Next-Gen Flame, Fortress Scales and a Panorama Eye
Defence moved into the wall. This generation holds encrypted caverns, keeps tunnels open only for creatures it named in advance, and breathes a flame that adapts to the shape of the attack rather than to a remembered face. A fortress is a body the dragon can live inside, which is why this generation built so many of them.
Behaviour · Territorial, methodical and strategic: decides who may cross, and treats the crossing itself as the event worth recording.

Epoch 3
The Cloud Hunt
2011–presentA Falcon Eye, Cloud Flame, Telemetry Wings and a Behavioral Gland
The dragon left the wall. This generation hunts behaviour instead of identity, gathers signals from every sky it has ever flown over, and kills a threat in the Cloud Mountains before the threat has reached any threshold at all. The shift is doctrinal as much as anatomical: the perimeter stopped being a place and became a range.
Behaviour · Fast, predictive and outward-facing: goes looking, rather than waiting to be approached.

Epoch 4
The Autonomous Watch
2013–presentAn Autonomy Gland, Identity Scales and Storm Wings
The youngest generation distributes the hunt: dragons that act without a rider, dragons that guard the identity of every creature rather than the gate they walk through, and dragons numerous enough to hold the sky as a storm front instead of as a body. Defence became something the sky does continuously, wherever the sky happens to be.
Behaviour · Autonomous, dispersed and swarm-minded: answers in seconds, and does not wait to be told which direction the threat is coming from.
