Viperwall is a keep built on the eastern shores of Ember Lake in central Varisia.[1] Its many towers and serpent carvings emit a sickening green light and poisonous fumes, so it is to no surprise that the place is greatly avoided by the local population.[2] Rumor has it that the castle was built sometime in the mid-fifth millennium AR by serpentfolk who traveled up from Sekamina through the Mobhad Leigh in order to create a surface outpost for their race. A connection to the Darklands in or near Viperwall is suspected, but lacks confirmation.[3]
