Human Names: This is more of a regional thing and my suggestion is to find a baby name book. (a baby name book for naming characters of any race is great!) For northwestern Tridon, I would use Irish or Scottish names. For Southwestern Tridon I would use good, old English names. For Tayke, Japanese and for Eastern Tridon I would use Native American names, and I don't mean Gold Eagle or Running River, I mean actual Native American names. For Ariella I would use Roman names or even African names. For any of these places snatching fun names from fantasy movies and books is always fun.
