Tribex are known to reside in the Plaines de Talenta, where plains Hobbits drive them using their Dinosauree mounts.

All forms of tribex share a few key features: triple horns, bony headplate, and a lion-like tail.

No statistics for tribex are listed in official Eberron products.

HobGobelins are also depicted riding tribex in official art.

Keith Baker has suggested on his website that tribex have a large rangel across Khorvaire and that there may be varying kinds across different climate regions.
