Silfergaths Bile is an enchanting forge inside Snowflake Manse. It is particularly useful for crafting items requiring cold enchantments. Two of the greatest magic items crafted on this forge are the artifacts Blizzard & Firestorm.
As its name implies, Silfergaths Bile is made from the bile of Silfergath, a frozen primordial at the bottom of the arctic sea Nautrek. In the construction of Snowflake Manse, Foropode had a vat of this stuff, rumored to have been taken from the Halatrax, splashed on the stone blocks that make-up the forge.
