Gern Blanston

 is a blue dragonborn wizard in the School of Necromancy, and a guest ally of Vox Machina. As a necromancer, Gern can animate the dead and keeps undead thralls, such as Carol, Coral, Fatty Arbuckle, and Stimpy. Gern is played by special guest Chris Hardwick.

Appearance
Gern is a blue dragonborn without a tail. When Vox Machina encountered him, Gern was wearing a red dance vest.

Background
Gern claimed to be a simple candlemaker, who makes enchanted candles with different effects. Some simply produce light, while others "create tragedy for people". Gern states that he was enslaved by his own kind who had tails, whereas he does not, and so dedicated his life to weaponizing candles using their scales. He uses mainly dragon scales and not other parts, though states that seeing them get blow to pieces is "merely for pleasure". After Thordak escaped from the Elemental Plane of Fire, devastating Cindergrove in the process, Gern arrived to gather materials for his spells.

When he met Vox Machina, Gern had four undead thralls with him, named Carol, Coral, Fatty Arbuckle, and Stimpy. During the fight against the efreet, Vex'ahlia offered to hold his broom of flying. After the battle, she slipped it into Grog's Bag of Holding and lied to Gern, telling him that the broom fell into the lava.

Trivia

 * The name "Gern Blanston" comes from a 1970s comedy album by comedian (and Satuday Night Live alumnus) Steve Martin, who pretended for comic effect during a bit that this was his real name.
 * Chris Hardwick uses an Irish accent when speaking as Gern.
 * Gern describes his backstory as having been enslaved by dragons and not dragonborn, and answers to questions about Thordak as though his bias is against normal, full-sized dragons, so it's unclear if he was one of the enslaved tailless dragonborn in Draconia or in a different circumstance.
 * Gern being a necromancer dancer and wearing a red dance vest is an allusion to the vest Cadence wore in Crypt of the NecroDancer.  Gern's undead thrall Coral may be a reference to Choral, or a reference to the way "The Walking Dead"-memes spell Carl Grimes' name. Carol might also be a reference from the same series, for which Chris Hardwick is the host of the after-show.
 * The name "Fatty Arbuckle" was the stage name of a lesser-known and somewhat-infamous comic actor from the early silent movie era, named Roscoe Arbuckle.  He was a contemporary of Charlie Chaplin.
