When he was very young one of the Jedi came to Qual's home village and sensed potential to be a Jedi in him. It was at this Young age that the Selkath was taken to Coruscant to train. His head was filled of stories of Selkath before him who had gone on to become Jedi masters before hime. He was so excited by what was to come. But when he got to coruscant and began the training he couldn't adjust. e missed his parents too much. The dry air bothered him and made him grumpy. The other children were to strange. And in the end he flunked out of the Jedi Academy before he was ever able to truly become a Padawan. He decided he could never go home and ran away before he could be shipped home. This was two Years befor Darth Sidious recruited Anakin Skywalker and Anakin killed all the youngling Jedi recruits on Coruscant. Many of those children were classmates of Qual's.
Qual tried to live on the streets but after two weeks he was weak and lost in the labyrinth that is the Cpital city of coruscant. Maybe it was luck, or Fate or the Force but something brought him to a doorway where he fell to the ground and started crying. He hadn't eaten in days, his skin was dry and starting to crack, and he didn't even know how to find his way back to the Jedi if he had wanted to .
This was the state that a Mon Calamari doctor by the name of Alten Brace found the young Selkath. He took Qual in, nursed him back to health and recognizing the aptitudes of the youngling, Alten began to train Brace as a medical healer and surgeon.
For twenty years he worked as the assistant of the doctor till a Rodian came into the clinic with a blaster burn on one arm and a blaster still held in the other. He demanded free treatment, and seeing as he was holding a weapon Qual's mentor and caretaker tended the wound as best he could. The Rodian left and not wanting anyone to know he had been there he Shot both Qual, and his mentor Alten. Leaving them both for dead the Rodian ran off into the night.
Hours later Qual awoke in the dark his side feeling like it was on fire. He tended to his own wound but when he went to check on Alten the older Mon Calamari had not had the Stamina to survive the wound... Feeling like there was nothing left for him on Coruscant Qual packed up what he could and sold what he could from the clinic and began to search for the Rodian that had killed his only friend.
Luckily for him the Rodian had a bounty out on him... and there were crumbs left for Qual to follow.
