Sylfaen is the second child of Muana and Tantus. Inspired by Duevalar's new form of life in Muana's material planes, they created Sylfaen to embody the volatility and free-will of Tantus' original design. Sylfaen was given dominion over the third material plane - a plane of joy, and the energy of life - where the fey were born to fulfil this mission.
