Berzio, working for years in his own selfmade workshop and often going for days without food, drink, or sleep, created the means by which Presence could be transferred from a scroll to a specially impregnated paper by use of a simple spell, which he named after his dog, Gnusto.
This paper, in turn, held the Presence even after the Incantation had been finished, solving the major problem in spell production. The euphoria which greeted this discovery was tempered by the finding that very powerful spells could not be transferred in this way.
Nevertheless, spell "books," which were capable of holding dozens of spells, were produced in great number, leading to the founding of a new industry.
Another advance in Thaumaturgy occurred with the finding that certain liquids and powders could be imbued with the magical Presence. Such potions are of great interest, although their limitations have prevented them from supplanting scrolls as the primary method of Incantation. The first of these potions, which obviates the need for food and drink, was given the name BERZIO, in honor of the great thaumaturge.
