Upon entering the Elemental Plane of fire, Scaldius just a moment ago met with the Earthen Ring that came in after the Farseer did. The Earthen Ring told him that they will bring an end to those who oppose his master Lord Smolderon. This would please him because he wants full control of the plane. Doing this act would gain an audience with Smolderon.[2]
After Smolderon obtains the title of Firelord, he sends Scaldius to the Heart of Azreoth. He then becomes the emissary of the new Firelord Smolderon as well as a champion of the Earthen Ring.
He has an invisible Follower recruiting spell with the following description: Follower: Scaldius — "Formerly a lieutenant of Ragnaros, Baron Scaldius now serves Firelord Smolderon with unwaivering loyalty. With the power and fury of the Firelands at his command, Baron Scaldius will incinerate any and all foes that cross his path." The spell is associated to a buff that says "Baron Scaldius attacks enemies with supreme violence and reckless abandon."
During the alpha, his role as a shaman champion was held by "Volcanis".
