Re: Herr D’s CFLs

Kobolds were creatures that sometimes lived in rock the way we live in air, according to medieval miners. Some of them stole mining equipment, caused cave-ins, warned miners of impending cave-ins, led miners to veins, stole ore, and occasionally claimed wages or sacrifices offered them to behave or assist. Various traditions referred to them as bluecaps, knockers, etc.

–Of course, some of them helped sailors instead and may have shared ancestry with dragons?
Ah, well, the biosphere for living ON land ‘in the air’ is a lot smaller than the one for living inside rock, so we wouldn’t exactly find them easily . . .
