Like most rat type beasts, the Scorched Earth Rats have the capability of somehow producing a Rat King. This king of rats takes different shapes and comes into being in various ways depending on what species it comes from. Sometimes a gathered clump of rats is controlled by a generated hive-mind that identifies itself as a rat king. A similar type of rat king is transformed from resurrected rat corpses that have fused together in death.
A few more magic-inclined rat type beasts can innately use a sacrificial ritual to summon a rat king. There were a few times a rat king had been recorded to have been created by the rats. They first made a large face-less statue of strange materials that they then prayed to, infusing their wills into it, the specific rat king had even gotten the nickname of 'Rat God' despite there not being any divine activity.
