A lot of unknown people.
An illustrious gathering of people, of whom a fair few have been identified. The bit of red sweater at the right is Fresh of TLT of Automation, the dark red hair in the middle is Red of Omega, the blue cap slightly to the right of the middle is Martin "LiesÚn" LiesÚn, and the serious-looking guy to his immediate right is Haq of Omega. The guy who looks like he is about to sneeze in his hand is AD (? - Lars) of TCB, crouched beyond whom can be seen the bespectacled form of Tanis of TCB.
