#Diluc as a reference for Time because it's the only real reference we have

[villvillhaitham]

Has wanting to write a Sumeru Akademiya Diluc AU led to me trying to figure out when who was where in comparison to Diluc's age? Yes.

Am I satisfied with the results? No, but that's only because things won't work out in ways I would have liked.

Anyway I want to share my data points and result, so:

General:

This was made with information from 3.5. Read before Kaveh release.

Lisa studied two years on the advanced track. I am assuming that a "regular course length" is three years and all characters in question had the intelligence to only need these three years for their studies.

Also I'm kind of assuming the traveller is in Sumeru about a year after the story begins. That's just personal preference and the only thing this really effects is Tighnari's age and time as forest ranger (as well as Cynos time as General Mahamatra/Matra)

Also all of these events have a little wiggle room of about 1-2 years, although some can be "wiggled" less

Data Points for Tighnari and Cyno:

Tighnari was investigated by Cyno when he joined the Akademiya for being suspiciously well liked. This implies that either Matra trainees start their work while still studying, which I doubt, or that Cyno's first year as a Matra was Tighnari's first year at the Akademiya.

Tighnari:

When the traveller reaches Sumeru he has been a forest ranger for at least a year with the reputation he has gotten. (Must have graduated at Diluc's 22 years of age at latest)

Lisa (our great connection):

Studied two years

Came to Mondstadt when Kaeya was Cavalry Captain and Varka was still around. This leaves her finishing her studies within a two year span between Diluc's 18th year (Kaeya becomes Cavalry Captain) and his 20th, where Varka leaves (2 years before game start).

Lisa and Cyno in relation:

Lisa refers to Cyno as a senior, so he must have been both a student and at least a year into his studies when she arrives.

Lisa and Tighnari: Tighnari's voiceline about Lisa does not sound like they met. Therefore I will be assuming they did not study at the Akademiya at the same time. (He only knows of her through Cyno, and she was quite the living legend at the Akademiya, so he would have heard of her then and not through Cyno later)

Also this version of the timeline is made to give Cyno as much time as possible as an active Matra when Diluc turns 18 (I wanted to prove to my friend why Diluc would beat Cyno in a fight) (I'll put wiggle room behind events)

Cyno starts studying at Spantamad when Diluc is 14 (D14)

Lisa starts her studies 2 years laster (D16)

Cyno graduates and becomes a Matra the year after (D17)

Lisa graduates the next year (D18)

Tighnari Starts his studies (D19)

Cyno becomes the General Mahamatra somewhere between D20 and D22,

Tighnari graduates and becomes a forest watchers at D21

This entire construct in relation can be pushed back 1 year

Cynos studies can be pushed back 1 year (everything else can stay)

Or 2 years (rest of timeline moves one year back because Cyno->Lisa->Tighnari) (Cyno can't have started at the same time as Lisa, who was not at the Akademiya when Tighnari started)

Cyno's Promotion time is pure and utter guessing game, couldn't find anything on it, so I just picked something I liked and it's there now.

Al Haitham and Kaveh are not on here because there is no possible point of reverence for either yet (although one could say that Kaveh consulted Tighnari for the flora around the palace of Alcazarzaray and has probably done so while they were in the Akademiya, so must have build that thing in the given three year period and... Yeah... That's like, not good enough, at all (especially because it's unclear to me whether he built it before or after graduation/it being his graduation work) and Kaveh is the only reference for Al Haitham (being a senior -> having started at least a years earlier))
