"I found Stargazer's algorithm in the data you recovered, except it's not an algorithm. They called it 'The Occlusion.' Love this stuff. My data crawler also pulled some old library records, showing who else accessed Stargazer's archive back in the day. Maelstrom!
She was the greatest military mind in history AND she's one of our smashed servers. It can't be a coincidence."

"If this 'Occlusion' spooked the Vex, maybe Maelstrom kept a backup of it on her server. She was a warrior, so go start some fights!"
