In Issola (book),ch. 15, a dragon who arrives with the Gods meets Vlad Taltos's eye and appears to know him. When Aliera wonders about it, Sethra Lavode suggests that Aliera ought to know this dragon. This dragon later takes on and kills a Jenoine by itself. Vlad says he doesn't think it's the same dragon he met on the Paths of the Dead in Taltos. Steven Brust has confirmed online that the dragon is in fact Devera, who presumably knows how to shape-shift.
