The Thames Valley Trail stretches for 110 km from its southern terminus on Southdel Drive at the Elgin Trail north terminus, to its northern terminus in St. Marys at the Avon Trail west terminus. This series of caches follows the off-road trail portions of the Thames Valley Trail (TVT) and are named for various fictional characters of the Star Trek universe.
Elnor is a Romulan refugee who Picard abandoned as a boy and was raised by the Qowat Milat, a sect of all-female warrior nuns. He joins Picard in his quest for Soji Asha.
The cache is hanging in a trailside tree.
