Then why not give Ascian the legendary assassin of Lady Umber .. 6 in movement ?
<DisplayName>Ascian</DisplayName>
<Description>You dream of a time before heroes, when titans ruled Elemental and those with ambition and courage were ruthlessly hunted and destroyed. You dream of Lady Umber sitting atop her onyx throne, keenly aware of all the threats to her empire. Her armies, her magic, her guile kept her lands safe. But when a more delicate hand was needed, when a rebel hero arose or someone showed to much magical aptitude, she summoned aide. From the shadows a silent form, nearly invisible but for amaranthine eyes and the wisps of faded magic, answered that call.</Description>
