“ Arune Spheres
Arune Spheres are hollow, blue reflective metallic spheres about 25 cm/ 10' in diameter (though some are larger). They are made of a thickish glass mirrored on the inside. When magical energies are flowed through the sphere, it produces a haunting tone, which can be varied by the type, intensity, and harmonics of energies passed through it. (It sounds like an electronic organ.) If multiple energy flows are generated, multiple sounds can be generated, some of which sound like mundane instruments. Masters of The Craft can replicate almost any sound in their memory with one. Though originally used as a training tools for those with The Power, it has been adapted to be a musical instrument. All it takes is someone with patience, medative training, and a touch of the Power, to use it. (Thus becoming the favorite instrument of anyone who was tested to the first level of the Craft, but failed to advance).”
“ An insignficant little species, the candlebug (or waxmoth) is a persistent bane for mages and merchants alike. Each the size of a small digit, these little scarabs thrive on wax and burrow up inside candles, ruining them. Sometimes a late-night worker will hear a crack and a sizzle as his candle expires, only to find the half-burned remains of a waxmoth squirming around on his desk. This is very annoying in worlds where candles are expensive...”
“ Mining in a certain area turns all exposed skin (maybe just parts that are actively disturbing the chemicals that cause the reaction) of the those doing the mining to a dark blue color. Will wear off taking as many years/days spent in the mine. ... meeting a party of blue-skinned humans armed with pick-axes etc. Strange disease? Demon offspring? Curse? If they meet only one ex-worker, they will very carefully listen to any stories he says, no matter if drunken or insane, or just makes up to get a beer.”
