So I will do my best to explain the timeline.
So ages are divided into 100 years each age being called a certain name like 'Dragon', 'Blessed', 'divine' according to what the divine (The woman says) there is a different Trivinter one for the Black Divine or the True Divine, Elves have there own, and I think Dwarves have there own as well.
But the Andrastrian calendar is what is mostly followed.
So I will tell you the Major Timelines of events, I am not familiar with the graphic novels so eh?
Ferelden gets free -> 9:02 Dragon (9th age, 2nd year, and dragon being the name given)
Cassandra was born -> 9:04 Dragon
Inquisitor (Kenric Trevelyan) -> 9:05 Dragon
Liliana -> 9:05 Dragon edit: 9:06
Dawn of the seeker -> 9:22 Dragon
Dragon age: Origins or the Fifth Blight -> 9:30 Dragon
Dragon Age II or the entire Kirkwall thing -> 9:30 Dragon to 9:37 Dragon
Dragon Age: Inquisition -> 9:40 Dragon
Trespasser-> 9:44 Dragon
Current year in the story -> 9:20 Dragon edit: 9:19 Dragon (and thanks @evergreen for the timeliness error)
Kenric is 15 years old.
If I am wrong plz do tell me.
Thanks for reading.
