Frustrated with writer's block, Auroth, the Eldwurm scholar takes flight from her lair to forge a new, heroic narrative—with herself as protagonist. Where most dragons originate fire, the Winter Wyvern stores unfathomable cold. Soaring over the treeline, she breathes a blistering chill, causing painful Arctic Burns. Frozen crystals form inside her gullet, shattering upon impact to Splinter Blast hordes of closely packed foes. Gentle with her companions, she holds them in a Cold Embrace, wrapping them in healing ice. Auroth has no time for would-be dragonslayers. Compelling her attackers to turn against one another, her Winter's Curse resolves the problem before any intruder ever sets foot in her lair.
Her next official appearance was in the comic "The new neighbors", which was posted on the 10th of February 2015 on the official Dota 2 blog. In the comic, she is depicted as an "artistic" dragon with interests in books who does not follow the traditional behavior of dragons razing cities to the ground.
Much like 军团指挥官, who is also voiced by Merle Dandridge, the gender of Winter Wyvern was changed from male to female with the transition from DotA to Dota 2.[1]
In DotA, Winter Wyvern makes use the model of the Warcraft 3 version of a frost wyrm, a well known undead dragon type from the Warcraft universe.[2]
Winter Wyvern's response when meeting 斧王 as an ally, ▶️ "In this world, nothing is certain but ice and axes" is a nod to a quote by Benjamin Franklin, which states: "In this world nothing can be said to be certain, except death and taxes."[3]
Winter Wyvern's response, ▶️ "Winter is coming. Winter Wyvern that is." is a reference to Game of Thrones, specifically the motto of the House of Stark: "Winter is coming."[4]
Winter Wyvern's rivalry line towards 龙骑士▶️"I knew Slyrak, Dragon Knight. You're no Slyrak." is a reference to Lloyd Bentsen's political quip "... I knew Jack Kennedy... Senator, you're no Jack Kennedy".[5]
When the hero's abilities were showcased in The International 2016, Winter's Curse was cast on a Naga Siren, which caused her team mates, Gyrocopter, Ancient Apparition, Earthshaker and Storm Spirit, to kill her. This is in reference to how Aui_2000, who played Naga during Game 4 in the finals of the previous International against CDEC, was subsequently kicked out of the team.
