Khelen is Ranyhyn stallion and Jeremiah's steed during the Third Chronicles.
Hynyn and khelen

Hynyn and Khelen in the middle of important stallion business.

As the misfortunate boy but stares and drools for the most part, the task of carrying him from point A to location B (but not to the bottom of C) does not prove much of a challenge. Therefore Khelen can spend rather more quality time with his beloved friend Hynyn off-scene, and furthermore neigh-giggle over the juiciest rumors of foul horseplay with Princess Cadance via the interdimensional equuslink.
