SureAI

I need to go to a library at the ruins of Treomar but drom the monastory boths paths lead to magicli sealed doors?
Do i have to go through the desert to reach it or something?

Sealed by order of a god?

Use -as you have been told- the roundabout south path.

You have to take the route through the dark forest, just becareful its a nasty place at times.
