Researchers learn whatever they can, however they can. Some are primarily scholars: content to absorb knowledge from endless books and correspondence, who only face danger when their inquiries provoke forces opposed to sharing what they have learned— particularly secrets mortals were not meant to know.
Researchers who become adventurers tend to favor fieldwork and exploration that add to their body of knowledge. Many come to regret their curiosity, but ultimately they simply can’t help themselves, or else they fear that knowing too little might allow dark forces to overwhelm the world.
