Mithril

Mithril is a rare and very strong and light silver metal-like glass. It can be said that it is only found in volcanoes or such an [obsidian] area. If alchemists study about transforming copper into gold, then blacksmiths dream of mithril, which is like copper but worth more than gold and steel. Especially now, after many horrible wars and disasters, mithril is very rare and very expensive.

Mithril armor is probably the best light armor, except for the Tiferet Armor the Lynks developed, combining [Yesod Resonance] technology with a special construction technique they have never shared. Of steel bullets, mithril armor can stop close range 9mm. If a new source of mithril was found, it could make the company very wealthy.

Also can be called orichalcum by some people.
