Des Por Vas

In The Forge of Virtue, the wizard Annon must escape from the Britain City guards, and prepares to use a Des Por spell. However, he then amends that to a Great Descend or Des Por Vas, which likely would allow him to move multiple levels beneath his present one, rather than a single floor.

 * "Quickly, Darrel--there's no time for warding. I cannot take you with me. There's a stairway behind the dragon tapestry. Get to the street and go home quickly. No one will follow you--not when they think they can follow me." Annon twirled his fingers through the cobwebs clinging to his robe and then dipped them in a powdery red stain on his worktable. "Des Por," he murmured. The spectacles fell from his nose. "Des Por Vas."


 * "Take me with you," Squirt pleaded. Another piece of wood struck the floor. The boy recognized the faded paint of the dovecote shutters. "Please--I won't be any trouble."


 * "No!" Annon sounded and looked more like a powerful mage. "Go home! It's too dangerous. You can't be found with a magician. Go home, now!"




 * Annon wrapped his fingers in spider-silk again, then touched them to the last of the red powder on the table.


 * "Des Por Vas!"
 * Incredibly, the magician began to sink through the floor.
