Though he seems normal at first glance, Iko appears to have supernatural powers that allow him to access codespace, as well as drag others in with him. He also wants to speak to Dragomir, and he sent Traveller off to find the guard. His motives are doing so, since he doesn't know who Dragomir is, are... dubious.
Iko is fond of peppering his speech with quotations. Whether or not he's making them up to sound more authoritative is anyone's guess.
