Kobolds, old German name for mine-spirit, are a type of heavily built, but short elf. They are natural steppers, and some speak english. Many, like Finn McCool, trade with other species, and like human culture. They are also sometimes called by humans "ringtails" or "urban foxes".
They sold iron-making, the wheel and advanced weapons to the beagles, thus multiplying the destruction of the numerous wars fought on Earth West 1,617,524.
They also appear to be able to use the soft places.
Like most of the stepping humanoids, kobolds are not found beyond the Gap.
These are where we get goblins from and are also natural steppers. The Kobold have learnt to talk to humans but generally cannot be trusted. They look out only for themselves – the best way to describe them is they are basically a race of Mundungus Fletchers from Harry Potter.
