+ Sesshō's Links
After being created by Adrian, Sessho ran immediately to Adrian's brother, Location. Location was the only other being that Sessho knew, besides Adrian, and he didn't know where else to go. He is very impressionable, as he was just created as a blank slate, and tends to mimic Location often.
Location became the unplanned guardian of Sessho after the former escaped Location's brother, Adrian. Normally, Location wouldn't care enough to let the smaller Alkarnabi stay with him, but since he himself understands how hard being around Adrian can be, he made an exception for Sessho.
Sessho greatly fears Adrian and does not like him at all. This is what led him to seeking out Adrian's brother, Location, as his caretaker instead.
Adrian is Sessho's creator. Through seeking to create life with his own paws, Adrian happened to put together the right pieces at the right time, and thus created Sessho. Since Sessho's creation, Adrian hasn't been able to recreate the conditions that led to Sessho, which has frustrated him greatly.
While Adrian doesn't like that Sessho ran off, he is pleased that Sessho is at least staying with his brother, Location. At least Adrian knows where he is.
