History
The Skrull Headquarters was the base of operations on Earth of the Skrull faction that had allied itself with Apocalypse. It was located half a world away from Egypt, the base of operations of Apocalypse himself.
At the base they were experimenting on Skrull mutants to reestablish the lost genetic strain of the Warskrulls. The base was infiltrated by the X-Men and destroyed by Death as it no longer served Apocalypse's purpose.[1]
