The Spiritwalker Trilogy (starting with COLD MAGIC) is my attempt to write “an Afro-Celtic post-Roman icepunk Regency fantasy adventure with airships, Phoenician spies, and the intelligent descendents of troodons.”
There’s a quite interesting discussion of colonialism and post colonialism (specifically with regard to fantasy and science fiction and her own work) in N.K. Jemisin’s post Considering Colonialism. In the comments, Jemisin mentions that she thinks Spiritwalker might be a non-colonial narrative.
I suspect it is difficult if not impossible to write non-colonial narratives in our colonial and post-colonial world when writing from the perspective of a culture that has done its share of colonizing. However, I believe the point is to examine other ways the world could be (and is, outside a certain narrow range of vision) and open a window onto them.
