While you were working and typing on the Computers, You got a ring call from the phone beside your table, You accepted the call, and it was Wallace Breen your Administrator

"Sorry to suddenly do this and disturb you during work... I need you to meet me at my office immediately!"

He hangs up the call and you stand up and then you walk to your Administrator's Office, You knock on the door as he writes something on his notepad and he notices the knock

"Come In!"

You step into the office and then close the door behind you as the Administrator still writing something in his notepad you sit on the chair as he rolls his chair in your direction, Your administrator is "Dr. Wallace Breen" He closes his notepad

"Looking at everyone's employee records and that it's... About me calling you here because of Today and Yesterday... Hmmm... Things start not going so well, All I see is; Security failure to access/Testing not going well with scientists... It's just- you know? It's not average... and I wonder does Sector D anything happened?"
