As a scholar, Cyrus' only true passion in life is the pursuit of knowledge. He teaches at the Royal Academy in Atlasdam, where he hopes to pass on his knowledge to those younger than him. Always so serious and with his nose in the book, Cyrus is usually oblivious to anything and anyone else around him. With his overflowing amount of knowledge, Cyrus is quite useful with his detective skills.
Cyrus' Path Action is called Scrutinize, which is the rogue counterpart to Alfyn's Inquire. You can acquire information from NPCs that will prove valuable for the various Side Stories in the game, as well as uncover hidden items in towns. Unlike with Inquire, you will be able to use Scrutinize at any level, although you won't have 100% chance for it to succeed. If Scrutinize fails, then your reputation in that town will decrease.
Study Foe is Cyrus' talent and can be one of the better ones in the game. What this does is basically uncover a single weakness of all enemies at the outset of a battle. This essentially cuts out some of the guessing work that needs to be done when discerning the weaknesses and can be extremely helpful if trying to break their shields as quickly as possible.
