The Dragon Lord ( comic story ) Summary . Part one . The Twelfth Doctor and Clara land on an alien world , specifically on a deserted trail . Using his sonic screwdriver the Doctor picks up a power source . However , what appears to be a dragon suddenly swoops down , grabbing hold of the TARDIS . The Doctor insists that dragons are fictional creatures , so this one cannot be real . Heading towards civilisation while chased by several dragons , they meet a force field which the Doctor bypasses with his sonic screwdriver . The Doctor and Clara find themselves in a mostly Medieval village which nevertheless contains heavily advanced technology . The town ' s residents are angry at the Doctor , who " cast a spell with his magic wand " and arrived unannounced . Met by Lord Mortigan , the Doctor holds out his psychic paper , which holds the seal of the Hanging Towers and allows the Doctor and Clara " freedom of the fourteen realms . " They follow Lord Mortigan to his keep , where the forcefield generator is held . Mortigan explains that their kingdom was created for those desiring a simpler age of chivalry , heraldry , pageantry and pomp . The dragons are actually genetically modified versions of native life forms . Unfortunately , the Doctor classifies the force field generator as impossible to repair — and if it remains broken , the dragons are likely to take all of the planet ' s human life . Weezie explains that the dragons were initially given inhibitor chips which stopped them from harming humans — " until the Dragon Lord came along . . . " This being was angry at the humans ' torture and slaying of innocent dragons for no reason other than entertainment . He freed the dragons from the humans ' tyranny , reversing the roles of hunters and hunted . The Doctor considers leaving the planet , but Clara points out it is not his responsibility to choose which lives are worth saving . Realising she is correct , the Doctor formulates a plan to reason with the Dragon Lord , though Lord Mortigan and Sir Edryc Dragonsbane are sceptical of this idea . Mortigan is in actuality planning on murdering the Dragon Lord instead . The group meets a baby dragon , which Mortigan slays ; unfortunately for the group , the baby ' s parents chase them in response . Sir Edryc leads the group to a cave , but the Doctor and Weezie are missing . While the dragon cannot enter the cave , it uses its fire breath to attack . Edryc manages to block the flames using his shield , but the heat still poses as a threat for the three humans . Meanwhile , Weezie climbs up a tree to give herself and the Doctor a better idea of their location . A spear rises from the ground , just barely missing the Doctor . This allows Weezie to identify their location as once - popular hunting grounds which the Dragon Lord mined with spear traps . The Doctor sets off his sonic screwdriver to avert any other spears from rising : they are " shielded against sonics . " Unfortunately , though , the Doctor and Weezie are " sitting ducks for any dragon that happens to come across us and fancies a snack . . . " and , as luck would have it , a dragon arrives at that very moment . Part two . Weezie notices that the dragon appears to be hurt , presumably as a result of a spear trap . The Doctor realises that the Dragon Lord would not let a dragon blunder into his own minefield , meaning he can ' t be controlling the dragon . In fact , even with the help of his sonic screwdriver , the Doctor is unable to find a micro - chip , suggesting the dragon is not controlled by anyone . Meanwhile , Sir Edryc initially elects to fight the dragon breathing fire , before deciding to instead lure it with his shiny armour . Thanks to Edryc ' s self - sacrifice , Mortigan and Clara are able to escape . The Doctor tries to revive the wounded dragon using Weezie ' s tissue regenerator , but as the spear went right into its heart , it remains dead . Weezie displays surprising knowledge about tissue regenerators . she explains that she was once Lady Lousia of the Giants ' Vale , who won the hunting tournament every year ; one year she was poisoned by a rival team and revived using a tissue regenerator . Hearing that she managed to come back from the dead , the Doctor shuns Weezie , saying she doesn ' t even have the right to pick her way through spear traps anymore . Mortigan and Clara reach the Red Castle , where the Dragon Lord resides . Clara notices that the drawbridge is down and the portcullis is open . But the castle is far from unguarded : an excess amount of oil falls down , and Mortigan only narrowly manages to move Clara out of the way . The oil does not seem to be boiling , however , since Mortigan manages to survive . But a far worse menace soon greets them : another dragon . Thankfully , Weezie and the Doctor arrive on the scene , the latter using his sonic screwdriver to activate a gate and traps the dragon . Reaching the throne room , they find a copious amount of treasure : shiny objects stolen by the dragons . The Dragon Lord himself , who is also present , is nothing more than a dead body . Presumably he was killed by dragons , despite his belief that they were his friends . The Doctor and Clara manage to contact the others ' home world , which has sent rescue ships to bring the residents back . They all agree that the planet should be left to the dragons from now on : as Weezie points out , " It ' s their world , after all . It always has been . . . " References .
