Automatons

Some time during the Second Age, humans living on Ymir figured out how to use adonium to create their own automatons to assist in mining adonium. Rather than running on electricity, these automatons ran on the magic of adonium itself. Every automaton has an adonium core, which acts as the seat of its consciousness. However, not every automaton has free will or total consciousness. Many simply behave as their makers programmed them to behave.
