A Rediscovered Shrine?

This quest is given by Riansom in Antonica after you complete the Letter to Riansom quest (see related quests). You must be level 20+ to receive this quest.

You must visit the Shrine of Decay in the Thundering Steppes (+345, +3.33, +1183). This is far south and surrounding by gnolls. Get the update and return to Riansom for coin and experience.
