Lanister is looking to fix the rusty sword he picked up. He is informed by Musharib that removing the level of rust may render it useless since it would weaken the core. However, if he could get a high enough source of heat and reforge it with Adamantine, he could keep its properties and maintain its physical form. There is auto-smelting available in the forge.
Elara: I don't think we should just run into the vault. We need to be prepared.
