I got isekai'd into Dragon Age Inquisition

Inen was a regular human being in the regular world, an art major, spending time drawing dragon age fanart. When she woke up to cassandra yelling at her, a big green breach in the sky and pointy ears.
She is stuck here now, in Thedas. But she knows so much, she knows Solas isnt who he pretends to be, she knows what is bound to happen.
But letting Haven get destroyed again ? What if it could be avoided ? What if she could make new choices with the knowledge she has ? How would the companions react to finding out Inen is from another world ?

NOTE: The story doesnt quite stick to that of the game, more and more as the story progresses. Because her presence influences the world and because looking for the exact dialogue for every scene is exhausting.
