"A Gaia Tree is a legendary plant. So rare that it's almost mythical," the Doctor said, the grin returning as he looked up at the tree again. "Not only is a Gaia Tree unbelievably huge, but it's also a miracle in disguise. You know why?" The Doctor asked before grinning down at Robin. "Because a single acorn from a Gaia Tree is able to bring self-sustaining plant life to an entire planet. It doesn't matter if the atmosphere is toxic or the place is devoid of water, the plants will grow regardless and make even the most desolate planet a paradise."<br/><br/>"I never dreamed I would ever see one. Legends say that the Gaia Tree requires a very carefully balanced diet of nutrients and in large amounts, hence why they're so rare to find," the Doctor said before scratching his fuzzy chin. "But... I have to wonder why the Dalek's are interested in it. And just what is the connection between the tree and old geezers from the Viking age?"<br/><br/>The Doctor stepped back into the TARDIS and straightened his bolo tie. "To answer your other question; No, those aren't Dalek ships. Those are fleets of several hundred Daleks. And they're more than likely about to declare war on the tree."<br/><br/>Explosions rang out in the far distance as the Dalek's opened fire and began littering the side of the tree with hundreds upon hundreds of laser blasts. The Doctor winced as he watched fiery scars leap from the wood of the tree, for a moment it seemed like they were in danger of the Dalek's bringing the whole thing down on top of them.<br/><br/>But then, just as the Dalek's rained down another volley of shots on the tree, a bright flash of white light lit up the area. Rays of white bounced off the surface of the silver building and scanned over the Dalek fleet, causing them to burst into flame and explode into tiny balls of fire.<br/><br/>"Oh...now that's just incredible," the Doctor said with relish before jumping back into the TARDIS and tapping at the buttons. "A Gaia Tree that can fight back against a Dalek fleet. Now that is amazing. It's no wonder the Dalek's want in when there's so much fire power protecting that little building hidden away.
