Talk to Lord Crwys to begin stage 1.

See the in-depth article for the strategy to solve the puzzles and defeat the monsters in between waves.

For stages 1–5, it is best to work in reverse with the mirrors' beam (predicting the beam of light from the Seren seal) until the stages with locked mirrors.

Direct light into the centre (place/rotate mirrors as needed).

Use Protect/Deflect Magic and keep moving when Dark Lord is alive. You can either kill the enemies between puzzles or tank their hits.

Each puzzle completed saves, so you can leave for more food and return between puzzles/fights.

After directing the beam into the Crwys Crystal, there will be some dialogue.

Quest complete!

Recommended: exit the Grand Library and speak to Arianwyn to teleport to the entrance of Prifddinas, or walk there yourself. After a skippable cutscene, the city of Prifddinas will be unlocked.
