Five touchstone realities exist at focal points along the Grid. From each of these realities, a Warlock is chosen to act as one of five Guardians. Savasthar, a shapeshifting dragon-like being. Doomidor, a warlord from the Dark Ages. Argon, an advanced cybernetic organism from a techno-hell.
Tanith, an ageless sorceress. Zania, a power-mad, machine gun necromancer. Together, the Warlocks protect the Grid, thereby protecting all of space and time. They are the last line of defense against the awful forces of chaos that lurk in the darkness outside the Grid.
