Council of Stars

Council of Stars is a main quest in the third act of.

Synopsis
The delemgan of Elms' Reach, told the Watcher that Thaos has destroyed the route from Teir Evron to Breith Eaman. To reach him, they will have to descend through the pit in the Burial Isle. The gods are willing to offer great power in exchange for a promise to deal with the stolen souls in the manner of their choosing. There would, however, be a price for betrayal.

Walkthrough
You automatically get this quest after completing The Assassin at Large.

Enter Teir Evron (the Glanfathan temple) in Elms' Reach. Pick up the Luminescent Adra Shard from the altar on the right, and place it into the pillar inside the big circle in the middle of the room. This activates four pulpits surrounding the circle. You can interact with each of them to speak to the god whose symbol is closest to it. (The remaining gods are not available.)

The first time you pray to each god, you must correctly recite their ritual words. You can figure these out by reading the books in the bookshelves on the left and top wall of this room, or from the lore you've already encountered throughout the game - or just consult the table below. If you recite the wrong words, the god will end the interaction abruptly and summon monsters to attack you.

Once you've gotten through to a god, they'll give you a quest which you can complete in order to gain their favor. The four available gods are:

Note that you only need the favor of one of the Gods in order to continue the main story, but feel free to do all four of those quests if you want. After completing one or more of them, return to Teir Evron and pray again to the god(s) who gave it to you. This will gain you their favor.

Furthermore, each of the gods whose quests you completed will make you an additional offer: They will give you a boon (making you more powerful), but in return you must promise to make your endgame choice according to their preference. The boon is given to the protagonist only (as a permanent passive talent that stacks with everything). If you accept such a proposal but then end up breaking your word, it will dramatically affect the end-game slides.

It was planned to gain Wael's Boon which gives +10 Defense against confusion, +1 Intellect if you do not take any of the boons from the four gods. Unfortunately that possibility was cut from the game, and the boon is accessible only through console commands.

After you've completed one quest and discussed the resulting offer, you will be granted an additional 1458 experience points. On exiting Teir Evron you will have a surreal encounter with Iovara and one of her guards. A dialog will ensue.

Next, travel to the Burial Isle (from the pier in Oldsong). The Quest will complete when you jump into the pit (see also Court of the Penitents). WARNING! Jumping into the pit is a way of no return, it starts the endgame.
