Stone ankh
From Warhammer - The Old World - Lexicanum
A Stone Ankh is a device known to unlock the entrance to the Tomb of Queen Rasut, in Nehekhara.
Jacob Stacheldhorf obtained this key and wanted to use it to enter the tomb and recover the khephra amulet which would unlock the sarcophagus of King Kaseph, residing the Magnus Museum in Altdorf. He gave it to Heinrich Johann for safekeeping, but Clarissa Lohft found out about it from Alun Gartner and had it stolen and used it herself to enter the tomb. It is unknown whether other tombs in Nehekhara use such a device to seal their entrances.[1]
