Dragon's Cave

The dragon's cave is a massive underground cavern beneath Camelot Castle in which The Great Dragon (Kilgharrah) was imprisoned by Uther Pendragon following The Great Purge.

Some twenty years after the Dragon's internment, Merlin arrived in Camelot, and the Dragon began calling to him. Soon after, Merlin discovered the cave and the Dragon, and began visiting regularly for the creature's advice. What I want to know is, how the hell did Uther and his Knights capture him in the first place. I presume he had better knights back then because they were shit against him in the Last Dragonlord. I reckon they used Balinor to make him go to sleep or something like that and then made a magical chain to tether him to. I can't help but think that if you're supposed to be King, you should be able to imprison the dragon himself. It is inbelivable how Uther runs the kingdom. If i was Arthur I would try and kill him to relieve all pressure.
