The Tainted Sun

To reach

Claw Viper Temple Level 1 you must move through the surface desert into the

Lost City. Once you get there the world will suddenly go to night, and will remain that way until you complete the quest.

If you return to town

Drognan tells you he's been researching this lengthy eclipse and believes it to be the work of

Claw Viper. You must explore the perimeter of the

Lost City, and somewhere around it, randomly located, will be a passageway into a small surface area, the

Valley of Snakes.

There are never any monsters there, other than an occasional

Fire Tower, so go right on in. Once inside the

Claw Viper Temple Level 1, search for the

Claw Viper Temple Level 2 where you'll find the Altar of the Sun, which is causing the darkness outside.
