The mark consists of The word 'TEMPEST' in bold capital sans serif letters. The top left corner of the letters E and M extend to the left to form a small triangular point, with the top edge of the point extending from the top left edge of each of these letters. The letter P is open at the left side, with the upper left end of the letter angled downward and a small triangular point extending downward from the angled end into the open space of the P. A dark equilateral hexagon with rounded vertices and vertical sides is positioned to the left of the word TEMPEST, with a light hexagonal line located just inside the outer edge of the hexagon. The hexagon contains a stylized letter T that has a narrow vertical elongated quadrilateral with the lower sides being longer than the upper sides and two slanted rhombuses to the left and right of the top of the quadrilateral, where the left rhombus is attached to the vertical quadrilateral. A downward-facing lightning bolt shape is connected to the outer edge of each rhombus to complete the stylized T within the hexagon.
