Cheese Dragons are not actually alive. They are enchanted items of food that act almost identically to dragons. They have no need to eat, but they must “live” in humid environments or they will dry out and harden.

Caseusa was created in the same workshop that Corta Dharca was created in. In an attempt to create magical watches that spoke time, a mage's lunch of cheese and crackers mutated into a Cheese Dragon. Like Corta Dharca before her, she fled where, like her, she found safety in the caves. Once she arrived, however, she confined herself to the dampest parts of the cave, fearful she might die otherwise..
