"My lord... you have arrived, woof..." The Dragon Seeker clumsily stood up, fumblingly paying his respects to Gaven while stuttering, "Thank you for your assistance... I will work doubly hard... to repay the Spirit Crystal Stones you gave, woof."
Clearly, some Gnoll had already explained to him the Dragon Seeking Ritual Ceremony and the matter of the Crystal Stones.
"The Spirit Crystal Stones are the common property of our tribe and need not be borne by individuals. You only need to follow orders and continue to work normally as before," Gaven cordially asked, "How do you feel about the Dragon Seeking Ritual Ceremony? Did you find your own True Dragon? What abilities did you unlock?"
"Very well, extremely well." When it came to the Dragon Seeking Ritual Ceremony, the Gnoll perked up and no longer stuttered, "I found it, a great... Bright Great Dragon... I bathed in its light till I just woke up. My ability is to make food and water clean."
