Infant dragons are only encountered in their lairs or within two kilometers of them. Juvenile dragons roam their home planet, hunting for large series I lifeforms. Adult dragons prowl the spacelanes, hunting pirates and the occaisonal free trader. In combat they all behave somewhat the same, they use claws and flame attacks to take down any target that looks tasty. A satiated dragon will not try to kill attackers, merely disable and humiliate them.
Some dragons use tools to suppliment their natural attacks.
A dragon can only use modified heavy weapons and specially designed melee weapons. A few draconic fortresses have even been constructed from asteroids in certain lawless systems. All adult dragons have an inate understanding of drivespace mechanics. Many Orlamu have attempted to question a dragon about the mechanics of drivespace, which the dragons traverse with ease. All of their attempts failed miserably, as the dragons typically gave cryptic responses.
