The Avatar of Freya wants you to head to the Makers' Overlook in eastern Sholazar Basin and use the Activation Switch Theta.
We cannot stop now, <race>. You've triggered the first switch, but one remains.
The titans constructed a second vantage point where they oversaw their creations. You'll find it to the east, high in the mountains.
Pull the activation switch theta inside the overlook and the waygate will open.
