Tarn is a Travelled mage, having arrived in Xibalba in the year 153. He was quick to recover, but had to struggle for a few years re-learning magic under the tutelage of the Silver Twilight Lodge. He currently still maintains an honorary membership there, where he has been discreetly spying on members of the Lodge for information regarding their plans for the Temple of the Traveller.
A potent mage, he is principally concerned with spell research most days. The land he was travelled from derived some of its magic - which he personally specialized in - from the side-effects of technology, and thanks in part to Neither Nor's efforts in Londolond, he has felt some of his old power return.
