The Base Access is a room in the Sky Temple Grounds. This room is the Dark Counterpart to the Hall of Eyes, and is very similar. The room is accessed from a Portal in the Hall of Eyes. The room connects the Abandoned Base to the War Ritual Grounds, the latter is blocked by a Green Blast Shield. The room is almost identical to the Hall of Eyes except for three Inglets, along with two Light Beacons.
