As the topic question, where was he? I don’t remember see him when I did the events. After searching the wiki it said that “During the Molten Alliance’s invasion, he aided in raiding a Molten Facility, where he recovered a pair of Fused Gauntlets for himself”.
He soloed the Molten Facility as a Thief. It took him nearly the entire duration of the event but he finally managed to clear the last boss. Afterwards, he ran CoF path 1 to replace all the gold he spent on repairs. He is now hiding in Southsun, disguised as a tree, thanks to the Endless Mystery Tonic he received from a Black Lion Chest drop.
