Not being from a four-dimensional place, a case could be made as to him having been in this particular dimension before the actual universe had been formed in it. At the time of formation, he had been fighting hard against those that were doing the forming and shaping of it all, not knowing that his kind arguably had the same kind of creative capabilities as their enemies. The main difference was, Thagirion and his people like the infinite dark where they could simply exist in whatever manner or form they chose. With the incursion of the light in their realm, that much had suddenly been stripped from them and they had to fight just to hold on to whatever shreds of their reality remained. And now here he was, appearing to be no less human than the next person to stand near him.
These days, he found himself traveling from place to place to learn more of what this world had to offer, as well as one thing he had found out was quite interesting: Food. As an extraplanar being, he had never truly needed to eat a single thing in his entire life, aside from the time when his kind had all been lumped together and sealed away for millennia. At the time, he had to cannibalize his brethren just to stay alive, clinging to what power he had left and staving off insanity over a drastic loss of freedom and quality of life. Here on earthland, material beings needed to eat material things in order to basically not die. Though that concept did not apply to him very much, the fact that people really knew what they were doing when preparing the carcasses of other living beings for consumption was what had taken his interest.
Frequently traveling from one place to the next so that he could sample the local cuisine, coming to Shirotsume had been no different. What made the place stand out from other cities such as Crocus was that they had a different style of leadership here. But as was the case with most forms of authority here on the planet, he did not feel like laws really applied to him as much. That said, he had come to understand the uses for currency quite well, thus becoming somewhat of a collector of coins and even going as far as “paying” for his food and drinks. After eating an ungodly amount of food from one of the local chefs, Thagirion left the crowded portion of the city in search for somewhere where he could lay down in the darkness and just digest. Reaching the outskirts of the place, he noticed a worn-down building.
From the looks of it, it had only recently caught fire, but had been put it by whoever it was that had felt responsible for doing so. However, due to the extensive damage to the building, no one seemed to be living in it, leading him to believe that he would be able to venture into the place without any issues. Walking up the barely intact staircase, he made his way to one of the windows. From there, he looked out through the broken glass for a couple of minutes. Only seeing a few people when he did, it seemed that those that saw him were either startled or simply wondered why he was there. As he did not possess a magical power signature one might sense or use to remember him by, it made sense that some people were startled. After a few minutes of pondering, he wandered away from the window and sat down against the wall to get a bit of rest.
