All hell breaks loose when a new mayor/governor takes over, perhaps with fresh siege experience, and decrees that the Wall Line must now be enforced. What havoc will follow when the guards come in force to clear the 'debris'.
I agree CM. This to me seems to be a good attempt to recreate medieval 'scholarly' texts and to me he seems to be discussing the origins of fire in general, in much the same vein as frogs appear spontaneously from mud.
Good! For me these things make me overthink - how do such creatures come about? Did they recently adapt to draw energy from magic? If not, what did they use before intelligent races evolved and developed magic?
Where they the creation of some asshole god, or a wizard who wanted bugs to seek out magic items?
If a creature is transformed into another creature (say, a human into a dog), then that creature will become more and more accustomed to the new form until a point is reached where reversing the spell is impossible. A second transformation is possible, but the creature will have to go through the whole process again.
