Description
When the High Elf ruling council moved to Sanctum and ignored Prince Hylas's pleas, he may have felt slighted, but his behavior in Treants' Grove is appalling. The forest might be able to guide our response. Venture there and speak with the Spirit Guide.
Upon completion
Prince Hylas seems desperate to control the beings of the plane of life. This madness can only end in tragedy for us all. You did well to follow the Spirit Guide's advice. Disrupting those profane rituals has saved the forest and its dwellers from great suffering.
