Review: One of the very early Darkover novels
Rating: 5 out of 5

Likely the best description of the Trailmen in the series.  The Darkover concept wasn't fully developed at the time of this writing, but much of the ideas are here:  advanced mental abilities, a benevolent feudal system, and multiple intelligent species sharing a planet, sometimes rather shakily.
