At first there was no trace of the offender, but one of the station's SFI officers found a recording which showed that the FO of the Odyssey, Lt.Cmdr. Sarin, was in the turbolift together with Kroynian just before she was attacked.
Luckily, only minutes after the Odyssey FO was confined to quarters, it was discovered that the evidence had been tampered with, and Lt. Commander Sarin was innocent, but the real culprit could still not be identified. The 'real' attacker on the recording turned out to be a character from a holo-novel.
When a few hours later a security officer was found murdered near the station's primary computer core, traces of holographic activity were detected, and the holographic systems were taken offline for investigation. Taking down the holographic systems had not the intended effect however; an 'evil' AI was able to take over the station's computer and holographic systems. A staff meeting with the Pandora and Odyssey senior crew was interrupted by a hologram, and the AI revealed its existence, and the fact that the holo-emitters were under its control, to the assembled crew by firing a phaser (set to stun) at the stations CMO.
This put a premature end to the meeting, and while the AI started to create holograms all over the station and Odyssey, both crews split up into several teams: Part of the Odyssey crew was sent to locate all Odyssey crew members on the space station and escort them back to the Odyssey, while another team went to the Odyssey to secure the ship's main computer. A team led by CEO Holmes and ASTC Ryaanax went to Engineering to get back control of the computer and CO Janssens, ACSO Naragona and ASTC Van Geel went to deck 90 to disable the station's internal sensors.
Several teams are still battling the holograms in several locations on the station, although the AI seems to be losing territory.
