Harry was roughly 300 years old, though he felt much older, when he had encountered the Vulcan Starfleet officer gathering firewood near his cave. It had been a long time since he had been with his friends and remaining family. Ever since the plague that targeted people with wizarding blood had wiped out the entire wizarding population, he had been on the run. The doctors at St. Mungo's had tried to combat it, but to no avail.
And now, he was the last wizard in the universe. He had had to watch as Ron and Hermione and every one of his friends and family had succumbed to the illness that attacked their magic first and then their bodies. Harry had gotten it too and then when he had woken up after dying, he wished he could have stayed dead.
He had been awed by the first spaceship and the contact with Vulcan. The universe was apparently not as small as the governments had once thought. With that thought, Harry took up planet hopping, hoping to get lost and forget. He never stayed too long on one planet, as he had discovered once or twice that there were people who would like to own the last wizard in the universe. He had known that revealing the wizarding world's existence in the hope that the muggle doctors could help would have consequences. And, he had found it, being the last of his race.
He had taken to using an alias to better protect himself after he had gotten captured that first time. That was also the first time he had discovered that there were special restraints that dampened the use of any talent, including magic. He had eventually gotten rescued by a Starfleet ship and had taken a couple months to recover from that 'experience' onboard that ship. However, it hadn't been the worst he had endured over the past couple hundred years. Harry had definitely counted the second wizarding war with Voldemort the worst couple years of his life.
He had just come back from the space port when he had noticed a Vulcan with a blue Starfleet uniform on. Harry trailed curiously after him, as he was aware of reports that the USS Enterprise had stopped above the planet. The officer that he was following had a stack of firewood in his arms, which was even more interesting. It was just starting to really snow and hail which turned into a blizzard.
Just as he was about to turn around and lope back to his cave, he noticed one of the giant indigenous creatures that roamed this planet about to charge the Vulcan.
Not wanting anything to happen to the officer, Harry took off and planted himself right in front the man.
"You might want to cover your ears." Harry reached out with his mind to the Vulcan and then let loose a loud challenging roar. Harry had been here long enough for the local wildlife to know not to mess with him. Once he closed his mouth, he noticed that the creature had fled. He then turned around and looked at the officer, who was staring at him with an odd expression on his face. His eyebrows had both gone up to his forehead in surprise, though unexpectedly, there was no fear in his eyes.
Harry noticed that while he was standing there, the Vulcan had started to shiver even though he had on a heavy coat. Harry had not even noticed the rapidly cooling temperatures as he had cast a warming charm on himself. Vulcans must be more susceptible to colder temperatures. Might was well herd him toward my cave; it'll be warmer there. Harry slowly padded his way toward him and attempted to appear harmless, he only lightly nudged the man.
Giving a little start, the man appeared to come out of his amazement. Harry saw his right arm twitch as if reaching for his phaser, but with his arms full, he couldn't do anything. Harry gave a chuff and then ran ahead some and then back and repeated it. The man seemed to get the idea and started to follow.
Though, Harry didn't have to repeatedly run back and fourth as the Vulcan appeared to know where to go on his own. So Harry stuck by his side, though still a couple of feet from him. As they were walking back, Harry used his magical sight and turned his gaze on the man. He had felt something that came from him and now he could see that the Vulcan had a thin rope, only visible to someone with magic, that was tying him to... apparently the guy in the cave that was lying on the ground.
Listening to the two debate on what to do with him was at first amusing then not very much with the bemusement. Plus, he could see that the human had a broken leg and was very much in pain, while waiting for the Vulcan to splint it. Being repeatedly stunned was also not fun, however, he had learned to throw off a stun charge from a phaser a couple of years ago.
Finally, having enough, he shifted back to his human form. He chuckled when the human fainted. The Vulcan just stood calmly and lifted one of his eyebrows.
"Well, that went well," Harry teasingly commented.
"And who would you be?" the Vulcan asked, while walking over to the human and kneeling at his side, pulled out a tricorder from his kit, scanning it over the human. As he did so, the human woke up, groaning all the while.
"Did Bones just use another hypospray on me or did I really just see a tiger shift into a human?" he asked. Harry chuckled at that, though he didn't know who Bones was.
As Harry had a pretty good experience with Starfleet so far, he decided that there was no harm in telling these two who he was.
"I am Harry Potter and you guys would be...?" he asked. As he said his name, the human's jaw dropped and the Vulcan's expression was as stunned as a Vulcan could be.
"You're the last wizard! You are still alive!" the human exclaimed excitedly. He was brimming with energy and Harry saw him wince when he jostled his leg too much.
"I am called Spock and this one here is my captain, Jim T. Kirk," the Vulcan replied, with hint of a smile at his partner's antics. "Captain, you need to stay still. Your leg needs splinting and I can not do that if you move about."
Harry raised an eyebrow at the name. The name Kirk seemed familiar for some reason.
"Jeeze, Spock, be a party pooper, why don't you? He's the only wizard left in existence! I read the books about his life," Jim said while Spock went about splinting his leg.
Harry blushed at that, aware that someone had written books about him after everything had gone down. "Is there something I can do to help with that?" he gestured to where Spock was tending to Jim's leg.
"No, it would be easier if it was just me," Spock stated. It looked to Harry that he was well focused on his Captain's welfare. If the tales that Harry had heard about the captain of the USS Enterprise and his first officer were correct, then there were good reason for them to take care of each other.
"So why are you guys here?" he asked, while extending some magic to help with the pain in Jim's leg. Harry had found that if he saw anyone in pain throughout his life, than he had a really difficult time not helping. The minute he feels his magic do what he was guiding it to do, Harry saw Jim relax fully. Spock gave him a questioning gaze when Jim calmed down to the point that he didn't move at all. Harry nodded in reply.
"We got chased off from some diplomatic mission by some of the locals and our shuttle was destroyed," Jim replied. "Our communicators got shot and now they're not working. Bones is so going to be angry with me when he has to panic about me."
"Who is this Bones you speak of?" Harry asked, curiously.
"Oh, he's the ship's doctor and my best friend," Jim replied with a grin on his face. "He likes to fuss over me."
"This weather is not helping either," Spock added, finishing up Jim's leg.
"Okay, you two clearly can't go out in the blizzard," Harry glanced outside of the cave. "Why don't you guys stay here and comm the Enterprise in the morning. I can help with the comms, too."
Throughout the evening and night, the three of them shared stories around the fire that Harry started. Though, it was mostly Jim asking Harry about his past and getting excited when Harry gave in and showed off his patronus. Eventually, Jim fell asleep and Spock soon followed.
After the two of them were asleep, Harry cast his patronus again. Prongs leapt from his wand and stood patiently in front of him.
"No enemies tonight. I need you to take a message, though. Get to Dr. McCoy on board the USS Enterprise and Lieutenant Uhura and let them know that their captain and first officer are safe and sound," Harry stated. He watched as the deer bowed its head and then disappeared.
And Harry soon followed Jim and Spock into sleep, though he shifted back into his tiger form and curled around the two. He made sure to keep the shields around his mind up, even if he knew that Vulcans were only touch telepaths.
