Inside the Temple of Lyria you will meet Abelyra Seranon M6(19), who will inform you of Lyria's blessing. In order to receive it, you will have to complete a series of tasks.
The first consists of filling an amphora with the water from three sacred springs.
One of them can be found nearby the gates of Rathir M5(11).
The second runs between Galafor and the Forsaken Plain M7(6).
The third can be found in the southern part of Galafor M7(6).
Having filled the amphora, return to the priestess to receive another task.
This time you need to head to the Lower Tunnels M6(13) and ridicule Nuer Bedlym, who publicly objects the order's teachings. For that, you will have to choose the following dialogue options: lower, upper, lower. You can also choose to use persuasion and focus on the middle answers.
After finishing the show, return to the priestess and begin the last phase of the ritual. This time you will have to give something to the order. There are three options:
1 - 10% experience.
2 - 77,200 gold.
3 - A magic gem (sometimes you might face a bug and this option won't appear).
The best solution is sacrificing 10% of experience right after reaching a new level, that way you will lose very little points. Regardless of your choice, you will receive a permanent blessing that reduces the cost of spells by 5%.
Inside the Temple of Lyria, meet with Seila Twayn. The woman is searching for the so-called Relic of Lyria which you can find all around the Plains of Erathell. In return for each of them, you will receive a generous prize. The artifacts have been placed in the following locations: Dolve Wayle, Dolve Arne, Virki, Rithen and Corgan Hold.
At the Scholia Arcana Grounds M6(20) you will meet a gnome named Telemachus, who will ask you to explore the Gloamthicket. The tunnels can be found in Acatha M7(13).
1 - Banshee
Go straight all the way and you will reach a chamber guarded by a group of monsters and a banshee. The large beast will keep on calling new ones, so get rid of it in the first place.
When it dies, you will be able to return to Telemachus to collect your prize.
Inside the library of Scholia Arcana M6(20) you should speak to Idris Theon. He will give you a book using which you have to pass a certain exam.
Start off by heading out onto the main square and pay a visit to Omnibus Arcana.
Your next destination is the bridge leading to Rathir M6(22). Having reached it, read the magic book once again.
This time it will lead you to Mel Aglir in Kandrian M4(1). The next location can be found nearby the road connecting Kandrian and Tala-Rane.
Defeat a group of monsters, check the book once again and return to Idris who' waiting at the Scholia Arcana library.
In order to gain more gold, you have to answer his question properly. The answer is "Principle of Observation". Choose it and you will end this mission.
