*Adrian gathers books about enchantment, infernal and Netherese lore initially trying to translate the phrase:
"vi NyISC irAw Gribortax"
Since he believes Gribortrax is the name of the demon he initially tries to focus if "vi NylSC irAw" is some sort of enchantment, and if it is he'll pursuit that lead trying to learn as much as he can about the enchantment itself (power, requirements, effects, etc...). *
One of the librarians stops to see if Adrian needs any assistance. When he hears the words, he says he isn't sure what they mean, but it sounds extremely familiar to Netherese. He doesn't know any speakers of it at this time, however.
