Plot Devices: If Geese is the plural of goose, what’s the plural of geas?

Magical compulsions are bread and butter in fantasy and folklore- the noble hero swearing a binding oath, or bewitched with a slave collar, or given a geas- it happens all the time. It’s honestly a little unusual to see a work of fantasy without anything like it.

It’s also one of the most dangerous plot devices to use without damaging the plausibility and internal consistency of your worldbuilding. Why? Because power seems more power, almost without fail. If a tool of magical compulsion exists, a government, dark lord, powerful wizard, or someone would logically try to use it on as many people as possible, barring constraints. (Plus magical compulsion itself is kinda disgusting.)
