The Machinations of Balgrum
Vox is the alchemical slurry used in most Rune-Core engines, as well as other devices. Its key ability is the insulation and magnification of the magical energies extracted from the rune stones. It does “degrade” over time, becoming supersaturated with energy and needs to be replaced every couple of years. As much energy as possible is extracted from the slurry and converted back into azoth, with the remains used as “life-blood” for various types of golems.
