Majestrum

Source: Taken directly from Ink Monkey Bones #4 on Eric Minton's blog.

Majestrum is a hard, dense metal composed of six parts Orichalcum, four parts Soulsteel, one part Moonsilver and one part Starmetal. Although it appears a lustrous black in indirect lighting, when illuminated directly it throws off a golden sheen.

Majestrum both resists and distorts the flow of Essence, making it useful in magitech circuitry. In addition, when forcibly infused with Essence, it harmonizes beautifully with magics of dominance and control.
