The Manastream

Said to be the source from which all magical energies are derived. It is a powerful, invisible force that surrounds all life on Novaura.
  Sorcerers learn how to weave the energies from the Manastream into reality to create effects ranging from simple parlor tricks to altering the fabric of reality itself.
  Clerics learn to channel this force to cure disease and to instantly close wounds.
  Wizards spend their entire lives studying and creating formulae to bend the stream to their will.
  It is a devastating force, as anyone who has seen The Tear will attest to.
