Kyriotates of Jean can inhabit objects, how many Forces does a non-living object have?
One Force per object. However, GMs should generally rule that individual systems count as “objectS” here. E.g., a car has the body (with the seatbelts and doors), the steering, and the radio – to get them all at once, the Kyriotate would have to dedicate three Forces. And aircraft carriers might be a bit more than one Force even for just the body . . . Typically, for houses, one wall or floor/ceiling at a time is “small” enough to count for one Force. GMs are free to ignore these guidelines, but Kyriotates of Lightning get even more potent without them.
