Elder Safran had no idea how these black robes-wearing inquisitors managed to infiltrate their elven race.
As the Blackwood Elves were a race of assassins that possessed the protection of the 'stealth' runes, any human disguise and stealth would be rendered useless before them.
But, those inquisitors managed to pull a wool over their eyes by using a different sort of disguise ability. In fact, there was a disciple Elder Safran was extremely proud of among those 'defected' elves.
Even though Elder Safran's heart was filled with anger and pain, his duty to protect the World Tree caused him to summon forth a great amount of treants to ward against the black robed inquisitors.
In fact, Elder Safran even transformed himself into a giant bear to personally engage in battle against the inquisitors. He used his sharp claws and fangs to tear at any intruder that dared infringe upon this land.
