Heimerdinger is one of the most prominently featured characters in Netflix’s Arcane, but the show never explains just how old he is. Netflix’s adaptation of the popular video game League of Legends has been a global success, introducing fans to the world of Runeterra. The show makes several references suggesting that Heimerdinger has been alive for some time, but his age and race are never explicitly discussed. He is one of the only non-human characters in the series, so it's somewhat surprising that his unusual quirks were not addressed.

Heimerdinger is heralded as one of the most esteemed and innovative inventors in the history of Piltover. The series even mentions several times that Heimerdinger is one of the founders of the “City of Progress”. The various technological advancements that he achieved paired with the wisdom he’d acquired from his abnormally long life helped shape Piltover into what it is today. His knowledge of magic and altered perception of time are traits of his mystical race, a species of creatures known as Yordles.

Although he is the only Yordle character from the game in the Netflix show so far, Heimerdinger is one of 14 Yordle champions in League of Legends. They are a race of ethereal creatures from the spirit realm that usually take the form of furry little bipeds in the physical world. Most Yordles rarely stray from their home in Brandle City, a realm between realms that few humans have ever seen, but there have been accounts of Yordles across Runeterra throughout history. As a result of being from a different plane of existence, Yordles do not age in the same way as most other creatures and do not need to breathe, which is how Heimerdinger has lived to be 307 years old.

Heimerdinger in Netflix’s Arcane

It is difficult to say exactly how long a Yordle can live for. Most of them seem to live for at least several hundred years, but there are some that have existed in Runeterra since ancient times. The animation in Netflix’s Arcane makes Heimerdinger look to be growing old, but his physical appearance isn’t necessarily tied to his age. Fizz, an unusual amphibious Yordle, has lived for approximately 10,000 years and still appears youthful, although it is likely because he hibernates for extended periods of time. So while Heimerdinger may be one of the oldest creatures in the physical realm, his 307 years of life thus far may prove to be just the beginning.

Heimerdinger is one of League of Legends’ oldest champions, introduced shortly after the game’s release in 2009. He is tremendously popular among both fans of the franchise and citizens of Piltover, so it is unlikely that he will meet a timely demise any time soon. And after the success of Arcane’s first season, an eventual second season seems all but assured, which means there will likely be even more Yordles yet to come.
