You will receive this quest after speaking with Anca at the end of the "Between the Words" quest. She will tell you about a monk who might be able to help you in the fight that awaits you.
The history of Vale Sangora is full of secrets and uncertain records of the past. Who knows - perhaps while searching for ways to save my family and defeat Brencis, I'll be able to unearth something that will prove useful in the upcoming fight?

1. Look for Albertus in the Middens (2 Time Segments)
Albertus - a crazed monk scribe residing somewhere in the Middens, an abandoned district of Svartrau. Might know more about St. Mihai and his silver sword...
2. Follow the writings on the walls
Albertus - a crazed monk scribe residing somewhere in the Middens, an abandoned district of Svartrau. Might know more about St. Mihai and his silver sword...
3. Go to Svartrau Cathedral
St. Mihai is supposed to be buried somewhere underneath Svartrau Cathedral. In a hidden crypt?
4. Question people in the cathedral
If there is a crypt in the cathedral, someone is bound to know something.
5. (Optional) Investigate the cathedral treasury (1 Time Segment)
The cathedral treasury is bound to be filled with many interesting objects... Maybe even some connected to St. Mihai. But how to get inside?
6. Gain access to the cathedral library
The Svartrau Cathedral chronicles might have clues regarding the crypt's whereabouts. The library is closed, but perhaps there's another way to get inside...
7. Help the deacon find the caretaker
The deacon promised me access to the library - if I help him find Radu the caretaker first.
8. (Optional) Find the broken stained glass in the caretaker's shed
The broken stained glass depicts St. Mihai - maybe there's some clue on it?
9. Find Saint Mihai's chalice in the cathedral treasury
A chalice that once belonged to St. Mihai? Might be useful. But to get it I must find a way inside the cathedral treasury.
10. Find Saint Mihai's memorial stone in the courtyard (1 Time Segment)
A commemorative plate marked by St. Mihai's personal sigil - that's where the entrance to the crypt is supposed to be hidden.
11. Explore the crypt (1 Time Segment)
Finally! I've found the entrance to the crypt where St. Mihai was laid to rest. Hopefully his sword was buried with him...
12. Defeat Saint Mihai
St. Mihai - still alive?! But the centuries of confinment pushed him into madness... Before I could speak to him, he attacked me.
13. Ending
Mihai... Imprisoned under Svartrau Cathedral for ages, now dead - by my hand. Called me a 'dawnwalker' and spoke of someone called 'the Augurs'. More and more questions without answers... At least I have his sword now - it may be damaged, but it's still a fine weapon. Restoring it might prove worthwhile...
