I am this world's greatest bibliophile. My less intelligent brother can govern my land.
MWAHAHA I HAVE THE POWER!
Brother, how could you do this to me? I trusted you to be content as my minion!
Lalala, I can't hear you over the clinking of this money~
Prospero was the Duke of Milan. He would rather study than rule so he appointed his brother Antonio to rule in Prospero's stead.
Everyone has betrayed me... Now all I have is you, Miranda.
Prospero became enraptured in his studies and ignored his state. Meanwhile, Antonio gained power and influence. Antonio gradually manipulated those loyal to Prospero, shifting the power in his favor without any fight from an unsuspecting Prospero.
Fine, whatever, just free me soon.
I freed you, now OBEY me, minion!
The King, who was Prospero's enemy, paid Antonio to force Prospero and Miranda out of the gates where they would be killed. Antonio became the Duke of Milan.
I only regret that I did not succeed!
Now I am the ruler, you disgusting slave!
The Ministers sent Prospero and Miranda off in an old boat. Prospero and a 3-year-old arrived on the island.
Prospero found and freed Ariel, gaining Ariel's service in exchange for his/her freedom. Prospero took Caliban in and taught him language. Caliban showed Prospero around the island.
Caliban attempted to defile Miranda. Prospero stopped him, enslaved him, and took control of the island.
