Cinnamon is an undead horse acquired and named by Ian Hubert during the events of Dragon of Icespire Peak.
While alive, the horse belonged to Lady Fyrst before the destruction of Aldrigvinter in 3E221. The horse was buried alongside her in her tomb south of the city.
In 3E448, when the Phanden Four were inside her tomb to acquire the dragonslayer longsword, Ian found and claimed the undead horse and named her Cinnamon.
After the events of the campaign, it is unknown what happened to Cinnamon. Although Ian was presumed dead not too long after the events of the campaign, the status of Cinnamon was never confirmed.
