The barren tundra that was to become TCN Node #51 was the site of several mysterious occurrences long before construction formally began in 2072. In 2071, a GDI convoy carrying construction materials disappeared en route, and the Orca recon patrol dispatched to find it was lost in a heavy snowstorm. Fearing that the violent weather had jeopardized the construction effort, a GDI ground team was hastily assembled and sent to the convoy's last known position. On approach, the team reported no sign of the vehicles, but the transmission was abruptly cut off. The team was never heard from again. Another rescue was attempted, this time with a Mammoth Tank at the forefront, but eerily, this group also disappeared.
The disappearances unnerved the nearby GDI garrison, with many troops refusing to accept patrol duties that would bring them within the vicinity of TCN Node #51. Those that did sometimes reported seeing the outline of a woman in the distance, walking calmly in the raging snowstorm, leading to stories of a "White Lady" which haunted the surround area. The GDI base commander, needing to begin construction but unwilling to risk losing more troops, requested a Nod recon detachment to ascertain the fate of the missing personnel.
Several days after the recon team was dispatched, three of the team's fifteen members returned to base, accompanied by an unidentified young woman. At this point, all official records are sealed by direct order of Kane himself, leaving only a handful of witnesses to detail what happened next. The witnesses agree that the woman identified herself to the base commander as Alyssa, and stated that she had a gift for Kane. Immediately thereafter, the witnesses reported that a vehicle un-stealthed behind her, revealing a completely new, highly-advanced, Stealth Tank.
This Stealth Tank was sleeker than the 3rd generation model, painted snowstorm white and heavily armed and armored. One witness claims to have heard the vehicle's creator take sole responsibility for the destruction of the GDI convoys and patrols with this single vehicle. After an initial inspection, the vehicle was immediately transported to an undisclosed location, presumably to join Project Omega as the prototype for the next-generation of Stealth Tanks. Although unconfirmed, some reports indicate that the Stealth Tank was returned to its original owner several years later after extensive study.
Details regarding the enigmatic Alyssa remain scarce, leading to rampant speculation amongst the world's conspiracy theorists. One believes that she was in command of a Nod installation at TCN Site #51, one of the "Vaults" of Kane that housed Nod's secret projects. Another proposes she is a Human-Scrin hybrid, born from Nod's twisted experiments in the frozen wastes of Siberia, and incorporated advanced Scrin technology into her vehicle. The most popular theory suggests she is a descendant of Anton Slavik, raised in the shadows to one day become Kane's most brilliant general. Theories abound, but the White Lady remains a mystery, one to which only Kane himself holds the key.
