Political event
Although some fighting still existed among the Kingdoms, all of those whom wanted peace and prosperity agreed to follow under the extended rule of Ahmbra the Brave and dubbed him King of all Beasts.
Ahmbra was a powerful lion who was stronger than all others even in his oldest years. When he died it was said that no other would take his crown and that he would still rule them from beyond. Ahmbra indeed came to them after his death and guided them whilst in spirit form.
