Transcript[]

- Zabsi: Outlander! They say you are born of valor. Please, if you have kindness to match my brother, he vanished. Help us.
- Class: I will. Tell me what happened.
- Zabsi: We Lilin are forbidden to enter Shieldholm. But the Mother does not end our affliction. So my brother and I knelt at symbols of the Father, to beseech him. He began the words, then there was flash, and... Dradwyr was gone.
- Class: I can help you look for him. Just be careful where you tread.
- Follow Zabsi

Sacred Guardians attack the duo
- Oblucus: Vigilance.

After defeating the Golems
- Zabsi: No... these guardians protect the rite of Purity's Penance.
- Class: That must be worse than it sounds. What is Purity's Penance?
- Zabsi: A ritual to try heretics. And punish them. He... he can't be...
- Together with Zabsi, hurry to the Ritual Grounds

At the end of the hallway, more Sacred Guardians attack the duo
- Oblucus: Safeguard.
- After defeating them, continue to the Ritual Grounds

More Sacred Guardians attack the duo
- Blightguard: Restore.

More Sacred Guardians, once again
- Oblucus: Sanction.
- Almost at the Ritual Grounds

More Sacred Guardians again
- Primguard: Safeguard.
- Zabsi: (to the player) We're almost to the ritual grounds. Please, we have to move faster.
- After defeating them, enter the Ritual Grounds

Dradwyr undergoes Purity's Penance
- Dradwyr: I recant... nothing. Only harmony... will spare us the Father's wrath.
- Inari Conservator: You tread filth onto sacred ground, and curse the Father to look upon Him.
Penance will be yours forever.
There can be no harmony with the get of demons.
- Nearby Sacred Guardian attack the player
- Class: I need to break down the barrier!
- Meanwhile, with the rite
- Dradwyr: No... this curse... it is a test!
The Father did not want us to be apart!
- After killing the Guardians, break the barrier

The backlash stuns the Conservators, which brings the rite to an end
- Zabsi: Dradwyr! (runs to him)
- Inari Conservator: Outsider. You spread poison throughout our home. The Father will rebuke you Pone day.

The Conservators teleport away
- Dradwyr: (shakily gets up) I... I... can see still.[1] Thank you. Thank you.

Talk to the siblings
- Zabsi: Thank the Mother. Let us leave this wicked place, Dradwyr. I can help you.
The Inari will never understand us, never share their salvation. There is a fissure between our people too vast for any bridge. - Dradwyr: No, Zabsi... you are wrong. The Mutinous Concord... was no crime. The outsider is proof. Unity is a glory of the Mother and Father. We will teach them. One day.
(to the player) We owe this reunion to you.
