The monks of the temple carved out a passage in the forest, leading that unknown monster somewhere, but Brand dared not follow; who knows if the boss will turn back?
However, as a creature of Lord level, its range of activity encompassed the outer circle of the Trade Wind Ring. So long as Brand stayed within it, the chances of encountering a boss remained high.
Moreover, according to the consistent settings of the Amber Sword, the deeper one ventured into the center, the more likely they were to alert the boss. Completing the quest for Valhalla easily was evidently not straightforward.
Fortunately, the temple had excellent Grey Knights as scouts, yet Brand's own scouts were no less competent. The Fireclaw Lizardmen even had a slight edge—they weren't the most professional reconnaissance soldiers—but the mind connection between the travel mage and summoned creatures played a unique role in such an environment.
