Seraph Bunker

Seraph Bunkers are underground defense bunkers built for the Seraphs as part of Rasputin's system-wide network, reactivated by Guardians in Season of the Seraph. They sit in the European Dead Zone, the Moon's Ocean of Storms, Io's Echo Mesa, Europa (inside the Bray Exoscience facility) and Twilight Gap. Each has a Rasputin console selling upgrades and bounties, and a daily "Daily Bunker Buster" mission. The Twilight Gap bunker is a whole mountain complex with a launch facility linked to Seraph Station.
