When I started writing Kings of Infinite Space, my friend Sylke was reading the early chapters and providing feedback, and this influenced both the plot and characterisation. She also did some illustrations for me, including a map, and these can be seen on her website.
This drawing is a wonderful depiction of Hrana.
Hrana – warrior, thief, and mother of the vampire race…

Great illustration, Frank. I can see where the snake imagery comes in. I wouldn’t want to encounter this one!
She’s not so bad. Unlikely to kill you unless you do something to deserve it.
Good to know – just in case. đŸ˜€
