Jag'ur is a 'young' crystalpony voiceless. He stands twice as large as a normal equestiran stallion, and is still expectred to grow. His fur is dark grey, and the crystals and lines along his face and flank grow with a warm orange. His short, spikey mane and tail are a mix of the two colors. The crystals which grow along him are still small.

He is protective of others, but lacks self-confidence. He is one to blame himself should anything go awry. He spends his sleeping hours in the Crossroads Bar and Grill, where he can easilly be woken by Granymead should he be needed. He patrols Ponyville on the lookout for Criminal Scum late at night; which ended up saving Black Harmony when she was ambushed.
