Tyranny of Dragons
This empty steel shell clamors as it moves, heavy plates banging and grinding against one another like the vengeful spirit of a fallen knight. Ponderous but persistent, this magical guardian is almost always a suit of plate armor.
To add to its menace, animated armor is frequently enchanted with scripted speech, so the armor can utter warnings, demand passwords, or deliver riddles. Rare suits of animated armor are able to carry on an actual conversation.
