Begin the quest by talking to one of D2R Items the guards on the south-west side of the Sentinel's Watch waypoint in the Mount Zavain zone. The guard (Terell) asks the player if they've met one of his fellow guards named Ryston. 

The guard must look for Ryston however, he's fairly close to Sentinel's Guard - head west, towards the yellow circle on the map. Ryston will inform the player that he'd like more food options than what's receiving, and will ask the player to get him some Varanid haunches. 

Once these are obtained and then given to Ryston, he will start an fire to cook the haunches. However for Ryston, a massive Gorejaw Varanid appears and swallows Ryston whole. The player must kill the Gorejaw in order to return Ryston's service Badge to Terell to get the reward.

Some players might notice a purple skull appear in their map every now and then. These are boss creatures that are sought-after. This is classified as a side quest despite it being an unplanned event which can occur in any zone. However, the wanted bosses tend to be found in the same areas within a zone. 

These bosses that glow purple are not as hard as gold-colored bosses. They always have minions as well. In theory, this quest should be easy to complete, however, picking certain D2R Ladder classes will make it easier. All the player needs to do is hunt down and defeat the boss to earn the reward.

This side quest can be found within The Ancient Graveyard area of the Frozen Tundra zone. This area of the Ancient Graveyard is not an location that many players visit. It's a ghost-town, literally and metaphorically. One of the reasons is that the creatures found in this region have an irritating habit of cheap D2R Ladder Items trapping the player in the ice-filled ring.
