Demeanour: Mercator is supremely patient, while greedy, he can take his time to achieve his goals. being functionally immortal (correct me if im wrong) he can take all the time to ensure that his plan was coming together. however, when there is not grand plan to pursue and there is no need to be careful Mercator can also be hedonistic and enjoys the finer things in life. 

History: During his time as a Sapphirim Mercator watched over the wandering merchants and this was a fine job during the days of horse drawn carriages. unfortunately as the world began to industrialize and globalize, he became more enamored with wealth in the same way those he was to watch over did. eventually succumbing to the temptation during the fall. his time on earth was spent fighting for scraps of power with many other petty crime lords and other fallen.

before his position as a black marketeer was established a fight with another fallen had gotten his wings destoryed preventing him from flying, which was only a minor hindrance, as he preferred to teleport anyways. even before the loss of his wings he knew that the Saphirim and fallen here his most serious threat. eventually he learned how to read the auras of those around him, which seemed much more valuable than flying.
