"Atmospheric disturbance Robin," the Doctor replied before sitting up and shaking his hands free of drops of rain that soaked the palms of his hands. "The air tastes damp and clammy but the grass has been subjected to an unusual amount of moisture despite the atmospheric conditions," the Doctor said before drying his hands on his trousers. "In other words, whatever is causing the time disturbance has only begun very recently. Perhaps a few days, maybe a few weeks."<br/><br/>The Doctor looked around at the houses and grinned before rolling up his sleeves. He walked over to one of the houses and knocked on the door, as if greeting a neighbor, before waiting on the door steps with his arms crossed and feet tapping against the wet ground.<br/><br/>"We're not going to get anywhere by listening to the ground and fondling with the plant life, so we might as well talk to the locals and see what they have to say," the Doctor spoke before the door to the house opened to reveal a young woman pointing a sharp sword at the Doctors throat.<br/><br/>"Robin, I think I made a mistake," the Doctor spoke before taking a step back as the woman pressed the blade to his neck.<br/><br/>She was ginger haired and blue eyed, but had all the innocence of a saber tooth tiger. Her eyes burned with ferocity as she forced the Doctor back.<br/><br/>"Who are you?" She hissed at him, before turning her head to glare at Robin. "You're not here to take my father are you? Because if you are then I'll slice the head from your shoulders."<br/><br/>The Doctor cast Robin a look of concern. Clearly, with all the irregular happenings that had gone on in the last hour, the idea that someone was afraid of strangers taking their loved ones away was cause for concern.<br/><br/>"I'm not here to take anyone away," the Doctor spoke calmly. "Especially not the father of a tribe of proud viking warriors," the Doctor said before moving the point of the blade away from his neck with the tip of his finger. "Swords were a sign of status among the Norse. A warrior who wielded a sword was a force to be reckoned with."<br/><br/>The Doctor looked into the fierce eyes of the woman before scratching the bottom of his chin, "So why would you be so afraid of an experienced Norse warrior being taken away? Surely a fierce brute like your father would scare anyone off."<br/><br/>The Doctor's musings were interrupted as a howl echoed through the village. The woman cast the Doctor a look of caution before dropping her blade and closing the door in his face.<br/><br/>For a moment, the Doctor stared after her in confusion. But then, his head turned to the direction of the sound and a frown spread over his face as he looked on to the dark figures that were approaching the village from a distance.<br/><br/>"Robin, little bit of a history lesson for you," the Doctor began as he stepped away from the door and began adjusting his bolo tie and rolled up trousers. "Viking warriors had a very special set of soldiers known as Bezerkers. They were a group of fearsome fighters that donned wold skins and specialized in working themselves up into a frenzy so that they would pretty much rip their enemies apart with their bare hands when they went into combat."<br/><br/>The Doctor began to jog on the spot before casting a glance to the group of warriors that approached them on all fours, dressed in wolf skins and brandishing axes and clubs.<br/><br/>"I thought you may want to know, because there are a bunch of them approaching us right now," the Doctor said before sprinting as fast as he could across the wet ground. "Run Robin!" he yelled as he feet pushed at the damp soil.
