"As hot as desert sand and as fresh as spring water, a juxtaposition of the modern and the traditional." "Shocking and outrageous..." Though reviews varied wildly, the minute Istvan donned his costume, all criticisms fell away. Though better suited for a grand hall, even here he exudes the charisma of a superstar. Perhaps it's the aura of the "Shadowlord" himself that lends an extra charm factor.
