The Great Furnace of Grymforge
[The pages, apparently copied from a master tome, describe the construction and use of a grand forge in the Underdark.] Among the Sharrans dwelled the gnome Silouv Yali, whose talents for wizardry were known from Candlekeep to Sorcere. Under his tutelage, the Sharrans built the Great Forge, which could heat mithral with such vigour as to turn it to adamantine. With this astonishing metal, they could mould the finest blades and armour. Yet the jewel of Yali's eye was not the forge itself, but the protector he conjured from the magma to guard it - a construct said to be so mighty that no blade could fell it, and no spell could pierce it. [Instructions for operating the Great Forge are listed underneath.] Ingredients: raw mithral ore and a proper mould. Place the ore and mould into their respective chambers. Pull the lever to lower the hammer and prepare the ore for smelting. Open the valve to allow lava into the crucible, and drop the hammer again to forge the product.
