The Order of Hermes scrupulously credits the creators of most rotes, documents their uses and annotates their variants. Phoebe Tetramegestus of Chantry Sangreal (Marseilles) developed this simple Effect in 1443. With it, a magus tracks a living target based on the trail of slightly warm air his body leaves. The Forces Sphere lets her track the target beyond the immediate area permitted by the Time Sphere's retrocognition.

For this Effect, Phoebe received a Prix d'Honneur in the next Decennial Adjudication ceremony. However, she seems never to have used it, nor any of her many other inventive rotes. In the last nine decades of her life, she never left her Chantry.

[The number of successes on the Effect roll determines how far the mage can track the target's movements. Two successes covers the immediate vicinity, five successes a block, 10 a small town and 20 a city. The spell must be used within five minutes of the target's passing, or the trail fades — unless, of course, no other living thing or weather pattern has passed through the same area.]
