The Grave is what's left of Earth following its destruction in the Great Intersolar War. It consist of the planetary remnants of the planet and its core, it is a stark symbol of humanity's sacrifice and loss. Parts of the grave have flowed into a ring around Luna giving the moon a grim planetary ring occasionally peppering the moon with meteor showers. The rest is rough clustered in the orbit Earth once had surrounding the exposed core of the world.
Many humans from across The Last Hand travel to Luna in pilgrimage to witness the Grave and pay respect to humanity's past. Every year when the Grave completes its journey around the Soul is the recognized New Year within most Human space, and is a a solemn day where humanity celebrates loss, their dead ones, and the promise of a better tomorrow.
Mining or salvaging materials from the Grave is strictly forbidden and considered one of the gravest moral and cultural taboos. Desecrating the Grave is viewed as defiling the remains of humanity’s birthplace, a betrayal of their shared history and collective dignity.
LDF(Luna Defence Fleet) have taken the solemn duty of patrolling the Grave, ensuring no unauthorized vessels enter its boundaries. Violators are pursued and face harsh punishment, not only would a individual be swiftly executed, their next of kin would also be striped of their base human rights and imprisoned for failing to stop such a violation. The Grave’s sanctity is non-negotiable.
