Spencer Mansion (Earth-6738)

The Spencer Mansion was a state-of-the-art mansion complex designed to perfectly mimic a 19th century Gothic manor within the Spencer's family real estate, at the Arklay Mountains, on Origae-6. It was built by architect George Trevor for the trillionaire Oswell E. Spencer. During the xenomorph and t-virus outbreak surrounding Hadley's Hope, the Special Tactics and Rescue Service investigated the mansion, which became overrun with clickers, xenomorphs, and other creatures.

History
The construction of the mansion started in 2562, after the American architect George Trevor was hired by the trillionaire Oswell E. Spencer, and finished in 2567. Spencer hoped to use the mansion to carry on secret, illegal, and inhumane experimentation with the mysterious Chemical A0-3959X.91 – 15, which his former friend, Charles Peter Weyland and founder of the Weyland-Yutani Corporation, had died searching for aboard the USCSS Prometheus in 2493. Spencer believed he would be able to manufacture powerful vaccines, weapons, among other materiel, within the hidden laboratory in the sub-level basement of the mansion. Trevor and his family were taken captive by Weyland-Yutani and sent to the Spencer Mansion during this time.
