Pobre is probably allied with teh Azzies now that he is Toxic...vs. Amazonia.
Yucatan can be a good training ground for Toxics to send against Amazonia.
Amazonia is probably aware of this and is funding insurgent groups and runners trying to kick out Pobre.
Even though Pobre is a regular dragon, the dragon probably has some formidable mutations that make it a scary dragon.
Anyways the alliance between the Azzies and Pobre is one of convenience, once the dragon outlives his importance...I can see the Azzies invading Yucatan again and cleaning the place out. The toxics will turn on the azzies once the war is over.
