Vagabond

The Vagabond is a mysterious man who dwells in the Storytime. He is a gaunt figure in a long robe, with bright blue eyes and tattoos that appear to cover his entire body. He carries a plain staff, and is sitting vigil beside a fire. He is also wearing a symbol around his neck that bears more than a passing resemblance to the Talisman of the Balance.
We see the Vagabond twice in Dreamfall. When Brian Westhouse travels through the Divide in 1933, he arrives in the Storytime and encounters the Vagabond, who is not pleased to see him. The Vagabond demands to know how Brian could be there, and orders him to leave. From his demeanour, it appears that the Vagabond is waiting for someone, or that Brian's presence is somehow disruptive. He also warns Brian about the Undreaming, and seems to be in fear of it, though he makes no attempt to save Brian when the Undreaming 'attacks' him.
Zoe Castillo meets the Vagabond when she enters the Storytime, but he is much more welcoming to her. The White Dragon has described Zoe as 'belonging to the world of dreams', so she may be the person the Vagabond has been waiting for. The Vagabond explains that the Storytime is a place where the stories that create everything are told. He says that the two of them have to act before it is too late, as 'the Undreaming is unchained'. The Vagabond may be some kind of watcher or guardian to the Storytime, but whomever he is, he clearly needs Zoe's help. Given that he meets both Zoe and Brian, either he is also very long-lived, or time has no meaning while one is in the Storytime.
