Dugrit Merryhide - Legendary wyvern rider

Dugrit Merryhide was the world’s greatest wyvern rider. He was well known for his outstanding skill, his fast wyvern Crannu. The duo has won one of each of the races in Matonga, except the race in Clearwen. Despite having never won in Clearwen, they hold the record for most wins during a lifetime.
Dugrit was last seen during a race where he and Crannu were in first place when they were violently assaulted and stung in with the poisonous tail of a competitive wyvern. The duo lost speed, Dugrit bleeding from his throat, Crannu with a broken wing, and dropped from the sky, right in front of the eyes of the crowds gathered in the arena. They were never found at the foot of the mountain. Legend goes that they flew into one of the cavern holes in the mountainside and died a poisonous death deep in the caverns. Many have ventured into the haunted caverns in search of the legendary duo, but to no avail.
One of the reasons of the success of Dugrit and Crannu was the Gjerde-forged saddle. Partly made from rare aeroresin, its design has never been matched. It was commissioned as a one of a kind weapon, so no blueprints exist. The only hope a competitive wyvern racer has to ever find such a perfect saddle, is to venture deep into the caverns under Clearwen.
The incident led to a permanent ban of poisonous stingers on wyverns. Though the procedure is painful for wyverns, less humanoid lives have been lost since the ban.
