The Crypts of the Green Lantern Corps is a massive location on Oa where the deceased members of the Green Lantern Corps rest after their deaths. It is guarded by Morro, Green Lantern of the former Sector 666

History
The Crypts of the Green Lantern Corps was created by the Guardians of the Universe to guard the souls of all deceased Green Lanterns. Morro, the Lantern of the lost Sector 666, is the guardian of the Crypts.

After the death of Abin Sur and twenty other Lanterns following the reappearance of Parallax and its destruction at the hands of Hal Jordan, a massive funeral was organized for all warriors who lost their lives against the creature. There, Amon Sur, Abin's son, gave a speech about his father.

During the Infinity War, Thanos and the Black Order invaded Oa, killing hundreds of Lanterns and even two Guardians of the Universe. Thanos subsequently used the Soul Stone to resurrect those he and his followers killed, as well as the dead Lanterns at the Crypts to become members of his Parademon army.
