Etrenank Gate is 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 sync with the rest of the world, rendering it invisible. When all three external gates were destroyed Solaris phased back into sync with the world.
