Once Tenkai had passed by the clamor going on within the Nine Swords, he was able to clearly pick out the noise of whirring servos and hydraulics as the gyrocopter flew overhead. A rather curious contraption, the likes of which Tenkai hadn't seen since leaving Rome. The resurgence of Renaissance thinking back at the Vatican had led to a slew of modern-day Da Vincis creating all sorts of strange feats of ingenuity, and this one was no exception. This one was creating quite a buzz amongst the passersby, however, and it had just come flying from the direction of the Hive.
Tenkai was aware that there was still more work to do in that unfortunate ward, which was one of the reasons why he had not yet left Sigil in the past few weeks. Tenkai was doing what he could to put the restless dead out of their misery, but he was only one man, and the destruction KB had wrought on the Hive was deeper than any of them had imagined. To see destruction of that level led Tenkai to believe that the Sabbat clans that originally took control of the Hive either abandoned it during the Hard Times, or were all summarily wiped out by KB. Either way, the gyrocopter had come from the direction of the Hive, and now Tenkai was curious to find out what business the pilot had flying over it.
The monk swiftly took to an alleyway, safely out of sight of the general public before springing into the air with a powerful thrust of his legs. He bounded up the sides of the three-story buildings until he reached the rooftops, continuing his pursuit of the curious aircraft. He leaped across gaps and alleyways like some sort of French freerunner, his robe trailing in the wind behind him in a blur of black and blue. Catching up with a flying machine was rather difficult for normal human agility, but Tenkai was fortunate enough that the pilot was simply cruising by, waving at the people below. A man of his agility wouldn't have much problem catching up to it. It was the gaps between buildings that Tenkai needed to watch out for.
Once Tenkai was close enough to get within earshot, he'd call out to the pilot.
"Ahoy up there!" the monk said merrily. He had no reason to believe the pilot was up to no good, especially not with all those people waving at him. "Quite an interesting vehicle, sir!"
