The Black Order equivalent of the Red Order’s Fire Pit, the Obsidian Sphere is a large black ball (Value 14) mined from the Dark Side obsidian hills, and enchanted over the course of 3 weeks. The magic trapped within the sphere can then be used to sustain up to 4 energy levels of magic, whose areas of effect are doubled. Unfortunately the sphere must be covered in the blood of three Keldian sacrifices each year to continue working, otherwise it needs no tending, though Star Iron Imprisoned minds are sometimes set to watch them (if the bound magic requires some choice or guidance). The Mage’s involved in making the sphere must all sacrifice 1 Health forever.
Occasionally Obsidian Spheres are discovered in the ruins of the Ancients. These spheres are often dead, but sometimes appear to be maintaining effects millennia after their construction, with no sacrifices required. These spheres generally cease to work if moved from their original location. Many Black Order Sages have quested for the means to making such spheres. So far none have succeeded.
power+1 level of magic or +1 year of free functioning per power level, at +1 week per level. Free years are deferred until sacrifices stop.
