[Edi]

When wishing for population, the new population appears in a random province among the ones you control.

Wishing for population may also snatch military units (as in, whole armies, all units in the province where the population is taken from) along for the ride, but said armies do NOT revert to your control. They are treated as a magical attack on your province instead.

Sages have one astral normally, so they cannot lead ghosts.

All WAD.
