Chapter One
Pippin commits a preemptive strike against a low grade threat. Thus becoming war criminal; the international community turns against The Shire as the dangerous loose cannons they have shown themselves to be.
The fact they are nuclear armed leads to years of protracted negotiations; extremely harsh sanctions and the economic ruin of The Shire.
The remains of Mordor; rise up and become far more important on the international stage. As the injured party they telegraph this into a much louder voice than they should command. They oppose the Elves but have similar goals, the control and subjugation of the humans.
