Santiago appears in the early posts of Ancient History (1242). There he gives Roberto a task to rescue a colleague of his named Flavia who had been kidnapped. It turns out that Flavia found clues that she thinks will lead her to a lost Temple of Mercury and others wanted that information from her. Roberto and his fellows rescued Flavia who has now asked the group to come with her to try and find the temple since she fears that the people who kidnapped her will pursue her to the temple.
Knowing that more trouble was coming, Santiago might have sent Woad to help bolster the efforts to find the temple.
