One of the captains of the Stormcrows, Prendal na Ghezn is a Ghiscari sellsword. He is described as thick-set, with a broad face and dark hair going grey.
Tikaram is not thick-set. Note that Tikaram is much closer in appearance to what Ghiscari are supposed to look like than Dan Hildebrand, who plays Kraznys, and certainly would seem like he could come from a very different culture than that of Daenerys or Jorah.
The Westeros network consists of several different sites, including a forum and a wiki, for all your A Song of Ice and Fire needs.
