Haltalloy

Haltalloy is a metal alloy with anti-magic properties. It was created in Varawyn by Simone Stilfinch, in the year 20.15. It was designed to be a way to protect oneself against mages, and is commonly used for this purpose.
=== Properties ===
Haltalloy has fascinating anti-magic properties. Haltalloy cannot be damaged, manipulated, or even moved with magical energy. A wall made of haltalloy will prevent teleportation through it, or any kind of passage via Fluxomancy. Those who are able to use Metal Magic cannot use it on Haltalloy. Haltalloy will completely block magical energy from moving through it. If a creature has a shard of haltalloy inside them, it completely prevents teleportation, or dimensional travel. However, haltalloy is not as strong as more common alloys, such as steel. It is also a particularly heavy alloy. Haltalloy has an incredibly high melting point.
=== Creation ===
Haltalloy is a metallic alloy, mostly made from Aurichalcum and Lead. There are also smaller amounts of Iron and Silicon within it. Its production must be incredibly precise, a single percentage ratio difference will completely nullify the alloy's anti-magic properties. There are only two places in the world with the necessary equipment and precision to effectively create large amounts of haltalloy; the Valentine-Stilfinch Foundry in Varawyn, and the Abbey of Metallurgy in Whytehold.
=== Uses ===
Because of how expensive Haltalloy is to create, and how heavy it is, it is often used in thin sheets, since its properties are the same no matter the thickness. Secure vaults will often have Haltalloy lining the interior. Specialised anti-magic armour may be plated in Haltalloy.
