Enclave fan, not even knowing their origins...
Serious, learn lore, then discuss. : D
Enclave from Fo3 are survivors from Oil Rig, who used Vertibirds to escape during Chosen One's sabotage, there is no one guy from other place.
And next info, which propably you didn't know, but it pretty basic. In 2077 and for few next decades, there was only one Enclave base, Oil Rig. :)
