Ro's Vessel  

This quest is initiated by talking to Civean Il'Pernod in Butcherblock Mountains once you have completed Ro's Infernal Device.

First, Civean sends you to talk to the follower of the Burning Prince in the temple of Solusek Ro in Lavastorm. The follower in question is Marathan Allim, who is located in the library in the temple of Solusek Ro at -433, -61, -664 Copy . Hail him, and he will ask you to prove your devotion by defeating a number of his constructs. The constructs spawn in waves as a ring event in the library room. Once you defeat them all, you will get an update, and a hailable version of Marathan will spawn again. Hail him, and he will ask you to lead him to the Volcano in Lavastorm.

Lead Marathan to -138, 18, 69 Copy for the update. It is located near the lower mouth of the Dragon's Mouth tunnel that leads down from the volcano crater. Next, return to Civean to complete your quest and get your reward, which is a summonable pet. This also opens up the next quest in the line.
