After I get the dark suite I'm currently loooking around but I cant find the new temple.
After you get the Dark Suit and the Energy return to the Light World and go to the Temple there and add the energy. Afterwards return to U-Mos and he will unlock the way to Torvus Bog. In Torvus get the 3 Keys fight the Chykka and repeat.
After you return the energy to Agon go see U-Mos. Than go back and scan the doors. One will open.
In elavator accesses B & C (in the great temple) there are two missile expansions.
