Tyvollus Aluviirsan is an Elven High Mage who was born during the time of Cormanthyr's height. He transformed the stolen sets of Nether Scrolls into Quess'Ar'Teranthvar, the Golden Grove of Hidden Knowledge.
It is said that to this day he still watches over the Quess'Ar'Teranthvar, his body in stasis and his mind locked in reverie. Should he be separated from the tree it will collapse into molten metal. After 20 years or less, the metal will once again reform itself into the shape of metal scrolls that the Netherese were familiar with.
