Han Sen saw something descend from the sky. It was a man in green clothing. A fairly ordinary looking Sky.
That man's approach wasn't ominous like the Dragon was, and he rode down atop a swallow mount. The bird was a pretty black and white, but it was definitely a little too small. The Sky man occupied all of its back, and he had to stand precariously on it.
The swallow looked tired. It flew before Han Sen, allowing the green-clothed man to nod at him. Then, it landed.
The swallow flew away in a rush, as if it was actually fleeing. The green-clothed man spoke to the escaping swallow, saying, "Thank you for bringing me here. I will return the favor some day!"
When the swallow heard what he said, it started flying away even faster. It flew as fast and far as it could. Eventually, it disappeared from sight.
