En route, he encounters a mysterious phenomenon which prevents warp, along with several Romulan Warbirds. They intend to apprehend a dangerous fugitive allegedly responsible for the deaths of many Romulans. Sisko confronts the Romulans over their illegal presence in Federation space and is taken prisoner. Captain Jean-Luc Picard, now in command of the "Galaxy"-class USS "Enterprise" (NCC-1701-D), is sent to the system to locate and recover the "Defiant" and her crew. After learning of the presence of warp inhibitors in the system, the "Enterprise" destroys them and Picard's team assaults a Romulan starbase in the area, saving the "Defiant". The game then advances to 2380, following the end of the Dominion War (see "What You Leave Behind"), the return of the USS "Voyager" from the Delta Quadrant (see ""), and the collapse of the Romulan Empire (see ""). Captain Picard and the "Sovereign"-class USS "Enterprise" (NCC-1701-E), along with Admiral Janeway (Kate Mulgrew) aboard the USS "Voyager", are engaged in discussions with T'Uerell, who is escorted by several powerful Borg vessels. She reveals that she has assumed the role of the Borg Queen, having reformed the Collective into a tool of total logic in pursuit of her goals to eliminate all that is illogical in the galaxy. When Starfleet refuse to surrender, T'Uerell has the Borg begin to assimilate civilians on nearby planets. However, Picard and Janeway are able to co-ordinate a mass evacuation of the system. Meanwhile, several Romulan and Klingon fleets draw out T'Uerell's forces and lure it to the more defendable Deep Space 9 space station. The combined Federation, Klingon and Romulan fleets, assisted by Deep Space 9, then confront T'Uerell and her Borg forces. However, T'Uerell flees moments before her vessel can be destroyed. In another system, T'Uerell harnesses polaric ion energy from a nebula to provide a massive boost to her shields. She then opens a transwarp conduit from the Delta Quadrant to bring in Borg reinforcements. With the battle raging, Picard devises a plan to disrupt the conduit by towing two sensor platforms modified to emit a magneton pulse to positions above and below T'Uerell's vessel. This pulse destabilizes the polaric ion energy string, disabling T'Uerell's ability to harness its energy for her shields and the conduit.
