The Galactic Empire Prepares To Invade Alderaan

Darth Vader uncovered evidence indicating one of his children was adopted by a friend of the Jedi Order. Vader immediately deducts this person to be Senator Bail Organa of Alderaan, as he had long noticed that Organa's "daughter", Princess Leia Organa, had a far greater resemblance to him and Padme Amidala then to Bail and Breha Organa. Vader presented his findings to Emperor Palpatine, and asked his master's permission to retrieve his daughter. The Emperor, believing that he would be able to use Vader's child for his own purposes, and anxious to have some excuse to get rid of the hated Organa, granted Vader permission to begin preparing a assault against Alderaan. By the end of the year, the Empire was assembling a force to impose its will on Alderaan.
