Capture and Training
The exact time or method of capture for this Singetail is undisclosed, but it did happen at some point after the events of "Living on the Edge". Krogan is a knowledgeable but merciless trainer with no compassion for his mount. The Singetail is able to be controlled through force of will, a riding crop, and a dragon-proof metal bit. He serves as Krogan's mount around the Archipelago.
Krogan's Singetail is much larger than other Singetails. Though never mentioned, it could be considered a titan wing. It is blood-red with dark red to maroon muzzle, socks, and markings.
Krogan's Singetail is a wild-caught dragon and chafes - literally - at the bit used on him. However, he follows orders from his rider well, even without the use of a riding crop. As it appears through the episodes, it almost appears that Krogan needs to fight to control it less and less as time moves on.
Krogan's Singetail first appears in the episode, "Dawn of Destruction", as Krogan himself goes after the Dragon Riders on Dragon's Edge, and chases them off. He later personally searches for Fishlegs, who had fallen from Meatlug.
