It doesn't mean anything I just made the name up xD I don't really name my characters, e.g. my lions with names with meanings like in Swahili etc.. I just make them up in my head or choose one I like the sound of that I feel suits the character! Sorry for the random late reply D: !!
Oh alright, I try to name my characters with a name that has a meaning, that would fit them, like my lion and hyena characters I tend to use Swahili names as I think it suits them best. My Lupine characters Norweigen, Romanian, Russian, or some other European type of name. Still Jaheera is a pretty cool name.
I like names with meanings, most of my wolves are named that way, and for those I stuck with European names. However I went about naming my lions differently for some strange reason haha. European names are always very interesting and great to use though. I love Europe, such a beautiful place filled with rich history, beautiful landscapes and architecture, and great music haha!
