He is found in a hut south of Nazaire's Pass Camp. He has been researching the region and its wildlife, but requires the Inquisitor's help in many ways.
It is likely the Inquisitor will stumble upon quests leading them to Frederic before meeting the man himself.
In fact, Frederic's research supplies have been waylaid (see Draconology), and his collaborators have disappeared (see Frederic's Livelihood), but both can be found on the way from the initial entry point (Lost Spring Canyon Camp) and Frederic's camp.
Meeting the Professor will unlock the Assault on Griffon Wing Keep quest.
If prompted through dialog about his own safety in such a dangerous region, Frederic will mention he saw bandits, White Claw troops, mysterious black-clad people and even Grey Wardens pass by, but none have interfered with him directly. If Varric is in the party, he will remark how odd that is. The Inquisitor may later find an explanation on a table in Shimmer Stone Mine:
- Venatori Orders
- Remind your hirelings to leave the Orlesian fop alone. With our red friends leaving the area, Servis expects more from the White Claw efforts. I'm not explaining to him that you let those raider idiots kill our best chance at actually getting that High Dragon in reach.
Once How to Lure a Dragon is completed, the professor will bestow the A Manuscript of Some Authority quest. Similarly, after the Hunting Patterns quest is completed, Frederic will ask the Inquisitor to destroy the hunting traps placed by the White Claw riders in the area (Sharper White Claws quest).Abyssal High Dragon.
