Their physical forms disintegrated by the arcane anomaly, the trio’s souls were cast far into the astral plane to drift for time unknown. One awoke as a metal monstrosity, unable to speak and beyond recognition. Another awoke as a worm, knowing nothing of his previous life.
Call it fate or chance or circumstance, but the duo found their way to each other. While neither of them remember each other, their souls do, and they formed a symbiotic partnership. Lur (as the worm calls himself) speaks for the duo, while the monstrosity shelters the physically frail Lur.
*As for the artificer? Nobody quite knows.
