In the Teen Titans comics why did King Myand'r always make sacrifices?

Answer 1

As a child, his name was Mythus, and the Citadel wanted his mother, Queen Talathus as a slave to save Tamaran. His father, King Korithus said no and tried to fight them, but he was killed. His 2 brothers, Scrithus and Korthus, tried to fight them and were killed, too. Queen Talathus became convinced that her life could have saved her planet and family, so she told her son, Mythus:

"You will be ruler, Mythus. This planet comes under your protection. We are to serve Tamaran, to sacrifice for her good. Remember that, Mythus, whatever we must do to keep peace, do it. Whatever sacrifices we must make, make them. Tamaran comes before all."

That's why, when he became King Myand'r, to save Tamaran, he gave his daughter, Princess Koriand'r to the Citadel and then forced her to marry Prince Karras. His final sacrifice was when he he and his wife, Queen Luand'r sacrificed their lives staying on Tamaran during a war that eventually destroyed their entire planet.
