Does a human with zero celestial Forces have a soul?
Yes, but this is a very rare situation. Normally, a human has at least one Force in each area. Due to advanced age or other damage, a human might lose his last Celestial Force – or, as a GM may rule, lose access to it on this side of death. Such misfortunates are usually very close to dying, but they still have their souls and will go to the appropriate place when they die. Note that some souls will disband upon the death of the entity or through celestial combat. A living human with zero Celestial Forces will resemble a remnant.
