There were some advantages to being immune to the effects of sunlight. Kain had spent the day wandering the city and experiencing the delights to be found in the shops and businesses. He wouldn't go into how he obtained money from humans, but being able to pass himself off as human and manipulate their minds had its advantages. It was a pleasant surprise being among humans again, or rather a viable population. By the time the last few centuries arrived in Nosgoth, Nosgoth was a deserted wasteland. As strange as the people were, as unfamiliar as some of the technology was, Kain was enjoying being in a living, thriving city.
When it was nearly sunset, he transported himself halfway across the city. His bat form was useful for traversing long distances, and he arrived in no time at all at his destination. He arrived some distance away in a cloud of bats, that gradually coalesced into a human-like form. He teleported the rest of the way. He didn't want them to believe he was one of those strange vampires, with their ability to transform into animals.
"I'm glad to see you've arrived," he called out to them as he approached, his regular sword strapped to his back in a scabbard. It wasn't the Reaver, but it would do once they used the methods they had created to destroy these vampires.
He surveyed the individuals assembled. There was a man with dark hair dressed in dark clothing, a man clothed in rags seemingly, Kennedy, and a woman he didn't recognize. Right away he recognized the man was a vampire, but he didn't have the sense of the supernatural around him. Kain couldn't even imagine how that was possible, but the ancients had supernatural powers long before they became vampires, so maybe it was a biological mechanism of some sort. Perhaps this brand of vampirism was a natural state, not a curse. He said nothing to Kennedy, instead giving a short nod at her along with all the others. He didn't want to start any problems with her. That was in the past, and right now they had only one focus - to kill those vampires in his lair.
And then there was Petrelli. Even at this distance, Kain knew he was powerful. The power radiated off him in waves. Kain had never sensed anyone this powerful aside from himself, besides Vorador and Mortanius, and they were thousands of years old. Petrelli didn't look a day over 30. Kain knew appearances could be deceiving, but for him to amass such a cast amount of power so quickly meant he had to be extraordinary, for a human. Duly impressed, Kain allowed himself the briefest of grins before he turned serious.
"This is your area of expertise. I'll follow your lead," he told Peter Petrelli. Humble and subdued was a new experience for Kain - it didn't fit his personality at all. But when he was an aristocrat, he often had to ingratiate himself into the graces of others. If that was what it takes to survive here, then so be it. He was confident of his power back on Nosgoth, and that was all that mattered.
He could take orders. He had followed Vorador's when he was fighting the Sarafan Lord, and Mortanius' before him. And he wouldn't betray his companions - unless they interfered with his plans. But he had no plans here, so they were safe. And he wouldn't attack Petrelli and his gang for no reason. And that was at the heart of how he functioned. Kain did things for a reason - he wasn't some sadistic monster going around killing people for the hell of it, like these vampires.
