Rathan, Emeni, and many other members of the House of Constructs spoke out against Margrave Gharmal when they launched their attack on Bastion. Fearing dissent, Gharmal removed many souls from their constructed bodies and imprisoned them in the Etheric Vault. Emeni's soul managed to escape, and together, she and Rathan sought out the Necrolord forces at the Seat of the Primus. Rathan promised that he and Emeni would build the Necrolords an army of constructs far greater than Gharmal's if the Maw Walker helped them reclaim Emeni's body and rescue the other souls trapped in the vault.
The trio traveled to the Body Banks and, after gathering the necessary tools from the nearby Construct forces, used the assembly equipment to build a new abomination for Emeni's soul to inhabit. The Maw Walker then worked with the reborn Emeni to rescue the souls trapped in the Etheric Vault. Rathan took these freed souls to Butchers Block outside the Seat of the Primus, declaring that the spot could serve as a new home where they could create a force of new construct warriors to fight for the Necrolords.
