ARCANE TIMELINE
every Information confirmed by lore or the creators is green. Everything I found out through math is orange (because we don't know months, birthdates, exact ages etc.). Things that are purely my headcanon i'm putting in blue. red represents League Wiki information that has not been disproved by arcane canon, that said it's Wiki anyone can edit and is not the most trusted source when the dates don't include a source.
I edit this everytime I find out something new!
some background that is important for the timeline:
BN refers to "Before Noxus". Before the Runewars, there were several rivaling tribes of Noxi in Runeterra. But after the Runewars they had banded together into one nation, Noxus. They establish their own Calender, BN (Before Noxus) and AN which stands for "After Noxus".
"Zaun" was not build at the same time as Piltover. In League lore. Zaun, then called Oshra Va'Zaun, was build 3000 BN, it was part of the Shuriman empire and became independent after Shurima fell.
Valoran is the name of the continent the story of Arcane takes place in. Zaun and Piltover reside in South Valoran. Noxus resides in East Valoran. Demacia resides in West Valoran.
772 BN: Oshra Va'Zaun attempts to create a safe sea-route between East and West Valoran. Their plan is to create a passage with bombs, which results in them accidentally triggering a series of strong earthquakes.
Half of Oshra Va'Zaun sinks and poisonous gas leaks into the city. Janna, a goddess revered by sailors, hears the Zaunites prayers and blows away the toxic gas, becoming their guardian deity.
790 AN: Thanks to the passage, merchant clans aquire an immense amount of wealth and take residence in the newly developed district that was build over the Pilt River. They name it Piltover to symbolize it's position over the Pilt River. In honor of it's founding, they have their first "Progress Day". Heimerdinger becomes one of the founders of Piltover. He is about 114 years old.
940-950 AN: Vander and Silco are somewhere between their 30's and 50's but exact ages are unknown. Same goes for Felicia and Connol. They look like they are in their 30's or at most early 40's when they die. All four must be born around 940 to 950 but I couldn't really narrow it down. If anyone finds information from the creators, let me know!
957 AN: Mel is 26 during season 1 act 1, so she is likely born in this year.
959 AN: Jayce is born in 959 because he is 24 in season 1 act 1. In the League Wiki he is listed as born in 959!
958-961 AN: Viktor is born sometime in those years. Viktor is around Jayce's age. It's unknown if he is older or younger though
965 AN: Vander and Silco work in the mines and meet eachother. (Putting this in blue because this detail comes from the Arcane artbook and we don't know at what age they meet, we just know they worked in the mines together) This could also be the year the last drop is bought or build by Vander!
967 AN: Vi is 14-16 during the events of season 1 act 1 according to Amanda Overton. I'm placing her at around 16 years old. Which means that she was likely born in 967. This is probably also the year the bar flashback with vanco and felicia happens :). This is also the year that is listed as her birth date in the League Wiki! In the League Wiki she is listed as born in 967!
966-968 AN: Cait is around the same age as Vi. If we say she was 15 during season 1 part 1, she would be born in 968. In the League Wiki she is listed as born in 966!
970 AN: year Ekko is born according to the League Wiki! This might be a headcanon from Ekko's voice actor, but I have to fact check it.
972 AN: Powder is roughly 5 years younger than Vi, so she would be born in 972 at the earliest.
978 AN: Felicia and Connol die in the riot at the bridge when Powder is around 6 and Vi is around 11 according to Amanda Overton.
980 AN: Mel says she was exciled ten years ago in season 1 act 3. So she arrived in 980 in Piltover. Mel is around 23 here because she is 33 in s1 act 2 & 3.
983 AN: This is the year were everything from season 1 act 1 takes place. It's not only the death year of Vander, Mylo and Clagger, Benzo and Greyson, this is the year Hextech was invented, Shimmer development was completed and the year the timeline splits into two (one where Vi lives and one where Vi dies)
990 AN: the 200th Progress Day takes place in 1x4. The events of episode 4-9 likely span not even longer than a week, so everything in season 1 act 2 and 3 happens in this year!
991 AN: between 2x3 ans 2x4 3-6 months have passed. I don't know how months and vegetation work in Runeterra, but if Viktor had enough time to build a thriving community and grow and take care of crops, i'd say that 2x4-2x9 takes place in 991 AN.
997 AN: is the year the current "present year" of the League of Legends Universe. In future spin-offs we will likely reach this year at some point.
unknown dates:
- Dr. Corin Reveck (Singed) is born and becomes a respected Doctor in Piltover. He worked together with Heimerdinger but the two parted ways because Heimerdinger disapproved of the unethical and inhumane methods Singed uses to bring Orianna back to life.
- Orianna (Singed's daughter) becomes sick and dies/is in a comatose state. In League lore she becomes sick after trying to help Zaunites escape from a chemical spill.
- Viktor's age when he meets Singed, Viktor's age when he enters the academy and becomes Heimerdingers assistant. Amanda Overton revealed that their (non-canon) idea is that Viktor's parents used their life savings to buy Viktor a Piltover school uniform. Viktor sneaks into the academy and impresses Heimerdinger so much that he doesn't kick him out and makes him an assistant instead.
- Jayce's age when he and his mother are trapped in the snowstorm. The death of Jayce's father likely already occured at or before this time.
- Isha's birthday. She between the ages Powder has in 1x1 (6-11). Since she is wearing a miners helmet we can guess that either he guardian or herself has worked in the mines at some point. She might be getting chased by goons because she escaped her workplace... chilling thought.
- the exact age of Kino and Mel, the date of Ambessa travelling through a regions where she falls in love with a stranger and has an affair with him (in the blood sweat and tears music video she appears already pregnant)
EDIT: Jayce was 24 not 25 in s1 act 1, my bad. Edited it to be his correct birth year (959)
EDIT 2: In a watch party Amanda Overton says that between episode 3 and 4 about 3 to 6 months have passed.
EDIT 3: thanks @darlingitsagathaharkness, you are right. I found this post that pieced together the chronological order of events in season 1 act 2 & 3. That is one hell of a week.
EDIT 4: I found concept art of Mel that confirms that she is imagined to be 26 during season 1 act 1.
If you find any other date or event that can be included here, please let me know :).
