Transcript[]
- Head for the Great Hall beyond the Keep Courtyard

Upon approaching the doors to the Great Hall
- Class: Ugh. This place stinks like a slaughterhouse.
Too many bodies. Have they already taken this place?
- Inside the Great Hall

Soldiers slowly box in a cultist
- Viv Mesztros: You were told to hand over the stone. Akinees was very clear.
(stands up and faces the soldiers) As you writhe in the Dark Lord's maw, remember your pride.

Viv Mesztros kills the soldiers
- After killiing Viv Mesztros
- Class: At least they haven't found the shard yet.
I need to find the commander fast. He should be near if he's anywhere.
- Look for the Commander further into the keep

Beyond a battle between cultists and the defenders is a locked gate
- Standish: Halt! How did you get up here?
- Class: Let me speak to your commander. I know where the cult is headed, and I can help stop them.
- Standish: Another adventurer? Truly? Wait — behind you, stranger!

Cultists attack the player
- After defeating the Cultists, the soldiers open the gate
- Standish: Look at that! Quite the fighter, aren't ya? Alright, I'm convinced. I'll take you to Kenton.

Talk to the commander
- Commander Kenton: So you're the one who slew that mad priestess? We owe you more than I can repay. She's been ripping us out like weeds.
That beast of theirs owns the skies... and on the walls, everywhere we look, it's Hell's mouth wide open and grinning. Whatever you have for me, I hope it's a lot. - Class: I've destroyed their portals.[1] Now I need to get into the old prison — if they find the shard there, this will get far worse.
- Commander Kenton: Again with the prison? You're the second savior of Stormpoint asking after it today.
- Class: Who's the first?
- Commander Kenton: Calls himself Zatham. Cut down a half-dozen cultists in the halls without breaking a sweat. He should be up on the parapets now. We'd be lucky to have you working together.
- Go to the Parapets...

... and meet up with Zatham
- Class: Zatham?
- Zatham: I hear that you have turned the battle in ways these people could not. This makes us the same.
Let us fix our purpose against the fanatics. They seek this fortress and the prison below it, by air and and by sea, and I cannot guard both. If we are two, there may be a sliver of hope. - Class: What's your stake in all this? You're clearly not with the guard.
- Zatham: You have looked into the eyes of these fanatics, yes? They wallow in sin, like animals in mud.
They are guilty. They are stained. But a just death will cleanse the filth from their souls.
- Shumbeel's roar is heard in the distance
- Zatham: This terror... once again.
- The Howling Terror flies by
- Zatham: I will distract it. My charge is the air, yours the sea. Go, swiftly!

Zatham goes after the Howling Terror
- Return to the commander...

... and convince him to let you into the prison
- Commander Kenton: It... looks like it's headed toward the prison. We're lucky.
- Class: What it's after is in that prison. Let me follow. As long as it's distracted, you should be safe.
- Commander Kenton: Evil festers down there. We wouldn't have sealed it shut this long otherwise. I hope you know what you're doing.
- The soldiers open the gates leading to the lifts

Descend the Lift to the Abandoned Prison
