Doctor Fretan had the Poison Grimoire in his possession and from it, he drafted out the excerpt which he had given to Petri to study and comprehend—a task that she did perfectly well.
Fretan could have as well handed Petri the entire Grimoire and have her study the Poisons in detail but she was still a greenhorn in that area and to avoid the risk of her knowing what she shouldn't know at her level, Fretan settled with writing out the excerpt for.
The section of the Poison Grimoire that he had copied out for Petri centred around the extraction of poisons. That was one of the most basic steps to learn in the use and manipulation of poison as a healer.
Doctor Fretan dropped one of the boxes on the table and opened it, revealing a Blue River Toad that was trapped inside it.
The Blue River Toad was alive but wasn't moving and that was because he had knocked the animal out with some of his potions.
