Roguish Archetype: Loreseeker

Years were spent poring over old tomes and researching the secrets of the world in ancient libraries to attain the level of knowledge of a Loreseeker. With a personal goal to uncover information of the past and present, these rogues delve into long forgotten places so they can document every last bit of knowledge they can.

They use their knowledge of anatomy and nature to gain the upper hand over their adversaries, whether they are a simple group of bandits or ancient dragons that control armies.

These rogues usually work with groups or organizations with similar interests, bringing their findings and sharing it with their peers.
