Ubergast

Ubergast was a sage living in Amn in the mid–14 century DR.

Some time before 1356 DR, Ubergast observed that the informal handwriting in the untitled wizard's workbook known traditionally as Briel's Book of Shadows matched that in a letter from Briel stating his plan to found a school of wizardry in Baldur's Gate, preserved in the city's archive. This supported the supposed authorship of the book.
