Sestris

"The Crystal God", Sestris is the sixth born of The Twelve Pillars of Creation and the Nascent God of Magick (not to be confused with the Sylvari Gods of Magick: Synor and Zol ). He is most commonly depicted as a vaguely humanoid shape in a state of perpetual motion as he is believed to be "the hardest working" of The Pillars. 
His home realm is The Tempest .
