Glass-Horn Sentinel

The Glass-Horn Sentinel is a rare, majestic herbivore native to deep, undisturbed forest glades, where the barrier between planes is unusually thin. Roughly the size of a large elk, it possesses a lithe, deer-like body covered in silken white fur, dappled with pale grey spots. Its most striking feature, however, are its antlers—crystalline, translucent structures that refract light into shimmering rainbows when touched by sun or moonlight. They’re not true glass, but rather a magical calcite-like growth that grows in fractal patterns, unique to each individual.

Despite their beauty, Glass-Horns are not fey or magical beasts in the arcane sense—they are wholly natural, though attuned to the primal rhythms of the forest in ways most animals are not. They appear to have an innate sense for danger, corruption, and emotional intent, often refusing to reveal themselves to those carrying malice. When threatened, they do not fight—they vanish, leaving behind only a shimmer of light and a faint scent of pine and ozone.

Basic Information

Ecology and Habitats

Glass-Horns are solitary or form small family pods of no more than three individuals. They feed primarily on lichens, moss, and flowering plants, showing a strong preference for plants with minor alchemical or magical properties, which may explain their own faint resonance with leyline energy. Some scholars theorize that Glass-Horns help balance or redirect minor planar turbulence through the vibrations in their antlers, but no formal studies have been allowed—largely because no one’s ever been able to catch one.

There are no known predators of the Glass-Horn Sentinel, either due to their evasiveness or their spiritual significance. Among certain elven and druidic circles, they are considered omens of harmony, and harming one is a grave taboo.

"There are creatures that watch you pass with caution, and there are creatures that watch you as if weighing your soul. The Glass-Horn does neither. It simply watches—so still, so silent, you’d think it were a trick of the light… until it vanishes in a burst of sunlight and mist." — Victoria Pendrake , upon nearly mistaking one for a shrine
