The central unit of the four gate generators. It functioned in conjunction with three other gates, one in Ignas, one under the ocean at Sargasso point and a fourth located underneath the Ethos HQ. The three external gates formed a triangle around Solaris and worked together to create a barrier that phased Solaris out of synch with the rest of the world rendering it invisible to the rest of the world. When all three external gates were destroyed Solaris phased back into synch with the world. The Etrenank Gate was destroyed when Fei and his companions infiltrated Solaris after it was phased back into synch with the rest of the world. It was sabotaged by former Elements Jessiah "Jesse" Black and Hyuga Ricdeau aka Citan Uzuki.
