While commanders of Kharim have control over their troops, they also have
power over the souls that are in their possession. Sometimes, in the heat of
the moment, it might prove inevitable that additional help is needed in order
to survive from the combat as the victor. Controlled souls are more loyal than
living troops and therefore are quite optimal for performing tasks that a
single person couldn't otherwise accomplish, such as guard duties at places
where the surefire death awaits.
