I’ve been playing with digital ‘collage’ for days now, and the image below comes close to what I see in my head:
It’s not perfect but I did manage to create the ‘ramp’ which features in book 2. This ramp has been in my head for years :
‘A moment later, all thought of Vokh politics fled Kahti’s mind as the tunnel opened out into a cavern of mammoth proportions. Glowworms placed at regular intervals revealed a number of passages leading out of the cavern, but the young Trader could not take its eyes from the huge ramp that snaked around half of the cavern before disappearing through an arched opening near the roof.’From the second book of Vokhtah, title still up in the air.
All of the scraps of texture and shape  that went into the final, composite image were manipulated in Corel Draw 8. No idea what I’ll do with the image, but it will be handy as a reference if nothing else. Just relieved it’s done.
