So the spell Clone states:
At any time after the clone matures, if the original creature dies, its soul transfers to the clone, provided that the soul is free and willing to return.
Does the soul teleport to the cloned body or does it come out of the carcass and travel there? And if so how long does it take? Also how far can the soul travel? Can it travel indefinitely? Can it travel across planes? Can it enter through Demi-planes?
