Frederick is a major NPC in Dyne's The Thousand Thrones game.
Before the incident[]
While technically the property of Johann the Thug, he was most commonly seen riden by Elena.

The Terrifying Transformation[]
After drinking warpstone tainted water he mutated gaining daemonic horns, bat wings, a burning body and the ability to breathe fire. After returning to Marienburg, he was dismissed by Elena with a smack to the hindquarters, causing him to take flight and crash into the neighboring forest.
Since then, he has appeared once, coming to the group's rescue at the Reaper's Bounty, a coaching inn in the Drakwald. There, he idiotically crashed into a pile of combustible materials and set the besieged inn on fire, covering the group's escape before hovering off into the night (and once again crashing into the forest.)
