Bab 45: Lumora Prime 

The information described the past events.

Sarah was killed in a hit-and-chase. The attackers were after an unidentified object in Sarah's possession. 

Few weeks later, Sean returned to Planet Falco, his home. He found out about his sister's death and tracked her killers.

He came to Oporia for revenge. Unfortunately, the murderers had a powerful backer, an Earl-ranked noble.

Sean was disposed of by the Earl's soldiers.

Bang!!!

Zain punched the wall. He was smiling, however, the aura around him had turned dark.

He punched the wall. Again, and Again, and Again, and Again. His knuckles throbbed and the blood slid down the wall.

Yet, his mind could not register the pain.

"It's my fault…" 

The unidentified possessions in the report were potions Zain made.

Would this have happened if he had focused on helping Sarah? Probably not.
