Great details here: the velvet lumens, the red dust. The characters and equipment are McDowallian. Any reason not to have them just be the things they're disguised as? The image of the headless flame is excellent.
I very much like that the violet flame has other uses, and that those uses can harm the user or ruin the device.
The alien geometry is a nice touch, and I like that most of the encounters aren't combat-oriented... it adds to the atmosphere.
