Arch of Bones
Age of Sigmar
At the start of the Age of Sigmar, undead forces tried to reclaim it but where going to fail because of the Bloodthirster Khar'zak'ghul. Only the timely arrival of the Stormcast Eternals saved them from annihilation.
The gate takes the form of a huge arch, made of the remains of thousands who fell in combat.[2a]
