a tiny tyrant that always points north and never once asks where you actually want to go
means A device for finding direction—typically using a magnetized needle that points to magnetic north—or, in the drawing sense, a hinged instrument for scribing circles.
from From Old French 'compas,' meaning 'measure, circle, pair of dividers,' built from Latin 'com-' (together) and 'passus' (a pace or step)—the root idea being to 'step out' a measured distance. The drawing tool came first; the navigational needle borrowed the name later, perhaps because both involve marking a circle of directions. The same Latin 'passus' that gives us 'pace' and 'passage' quietly walks underneath.
