Jered Gan is ReGan's old master, the former Sage of Mirror Lake, and the eighth seat in Plant Hwyaden's Ten-Seat Council.

Appearance

Prior to the Catastrophe
He was ReGan's master and the previous Sage of Mirror Lake. Before he left, however, he stole some documents in the Sage's library for reasons unknown. Whether ReGan is aware of this is unknown.

After the Catastrophe
He joins the Plant Hwyaden and with his knowledge and magic powers, he pushed the frontier of development of new techniques together with Zeldys.
