(Capcom's primary storyline)
Though it was not the only facility developing Tyrants in mid-1998, Sheena Island's facility was geared towards mass-production of the new T-103 series.[excerpt 1] A prototype Tyrant model was also in production in the facility, known as the Hypnos-T Type. Other B.O.W.s produced at the facility were the new Plant 43 B.O.W.s, and the comparatively older Hunter α.
In November 1998 the t-Virus was intentionally leaked from this facility by Goldman, who intended to quash a plot against him and pass it off as an accident on escape. The Hunters and a number of the T-103s were released from their containment to rampage across the city, ensuring its destruction. The facility was later infiltrated by Ark Thompson and two children, Lott and Lilly Klein, who were in search of a means of escaping the island. A team of Under Takers, intelligent B.O.W.s armed with guns, was soon after sent into the facility by Umbrella in their cleanup efforts, which included the elimination of witnesses. The self-destruct system was triggered during the chaos, and Hypnos itself was released. Ark; Lott and Lilly are the only known survivors of the incident on the island as a result of this chaos, having escaped on a helicopter before much of the island was destroyed by the Tyrant Plant's detonation.
The facility was built underground, and was hidden under a mansion to hide itself.
