I believe I have found an answer to the mystery surrounding the photo Terminal.jpeg from the IRIS Halo 3 Alternate Reality Game that took place during the summer of 2007. This might not be important to some people, but I believe it may be interesting to those who took part in IRIS. The post might be updated a lot because of new information or new mysteries figured out.
The mysterious photo Terminal.jpeg might actually be the home of AdjutantReflex. When I first saw this photo, I figured it was either the home for AdjutantReflex, or the force that took him or her over. The home for this AI is clearly inside a terminal, because of the name and Halo 3 terminal sphere in the background. What makes me think it is the home of an AI lies in the background. If you look at the right inside of the Crystopheron, there is a blue light. This light appears like it is an AI. What makes me think it is AdjutantReflex is, of course, the Crystopheron, which seemed to be his main symbol until he was taken over.
At the same time as I have answered this, I believe I can also develop a hypothesis for the photo MB05032_09_25_07.gif. Whatever this new entity is, it could have either orignated inside a terminal, which I assumed because of the golden lines/circle and honeycomb background. However, this AI might also be living in the terminal which once belonged to AdjutantReflex. 09_25_07 was an obvious reference towards the release date of Halo 3 (09/25/07). But, as for MB05032, the MB could stand for Mendicant Bias, with the number 05032 possbly being a serial number for the AI (such as 05-032) . This would make sense, since the J symbol is the glyph for Mendicant Bias. You can see his glyph [=mendicant%20bias&filters[primary]=images]here](http://media.beta.photobucket.com/user/ARCThunder/media/Forerunner%20Symbols/mendicantbias01.png.html?filters[term).
