Sorin continued to stalk through the streets as its various residents slowly emerged from their domiciles. It was clear that this Viewer had stolen far more that the handful of people that Sorin had met from their rightful planes. Worse yet, Sorin was able to gather from brushing the minds of these abductees that this act of summoning "challengers" for entertainment was a somewhat frequent occurrence. This only infuriated Sorin more. The Viewer was actually a substantial threat to the Multiverse, and one Sorin would not stand for. Still, as he had earlier concluded, he had no means of dealing with him without playing along with these inane "challenges." 

The diversity of the city streets reminded Sorin of the city-plane of Ravnica, though it put him somewhat on edge. He would need a place to settle in for his (hopefully) short stay on this plane, as he refused to pack in the the rest of the herd at the "Oasis" building. He soon enough found a quaint manor, not unlike something that could be found in his home of Innistrad. 

Sorin invited himself in, and was quickly met with the objections of the mayor's residents. From what Sorin could tell, they were simple, homely folk. All the easier to deal with. 

"I will be requisitioning your home for the next month; perhaps longer, but hopefully not. Feel free to stay with neighbors in the meantime. I understand that this may be contrary to your own desires, but I recommend that you direct all of your well-reasoned arguments will to my sword." He said, a dangerous gleam in his eye.

The residents got the hint and scurried out. No magic, just simple persuasion. There was a reason that the vampires of Zendikar knew him as the Mortifier, and it wasn't because he had an open and approachable personality.
