Uniting the five colonies was critical for the freedom fighters to overcome the dominance of the Black Queen. Standing together they had a chance to determine their own destiny, but apart there was little hope of escaping the tyranny of Casandras ghastly domination, and with Silver Citys queen lost in the storm, there was no one else who could convince the outlying colonies to stand against the two wicked sisters.
The termite queen couldnt do it, since she was a natural born enemy and no other ant held a high enough rank to address such issues with ruling monarchs. Queen Amy had to be found before it was too late to prevent the looming annihilation of her colony or others and the freedom fighters were using every resource at their disposal to find out what happened to their influential queen, who was brave enough to defiantly stand against her own mother.
