The rough, gray stones of Aethelgard stand once more as a silent sentry over Douxel Vale. For weeks, the scraping of trowels and the thrum of restorative magic have echoed through its ancient halls. The fortress, home of the Laetora Gravebound, is slowly being woven back together—its deepest scars mended by shimmering ribbons of dark obsidian rock, like solidified shadow holding history in place.

Yet, for all the progress made by the forces securing it, Aethelgard refuses to yield all its secrets.

The tragedy, however, is that some secrets should have remained buried forever.

The air in Douxel Vale has grown heavy, thick with the sulfurous stench of the Abyss and the suffocating chill of the Shadowfell. When the group returned from their fateful expedition, there were no cheers of triumph, no celebratory feasts, and no warm welcomes. Instead, they met an uneasy, silent homecoming. The very sky above the vale seems to bleed a bruised, unnatural purple.

Before the vanguard could even reach the gates of the restoring fortress, a familiar shape materialized from the warping fog.

Nyx, the strange shadow creature who had so eagerly offered his services to unlock Aethelgard's secrets, did not greet them with his usual clever, fractured grin. For the first time since the group has known him, Nyx looks visibly shaken. His shadowy form flickers violently, spilling erratic, nervous static into the air. Without a word, he ushered the party away from the main roads, secreting them deep into the damp, claustrophobic darkness of a hidden cave in the Veiled Warrens.

When the shadows of the cave finally enveloped them, Nix turned, his form trembling with a mixture of terror and disbelief.

"You fools," Nyx whispers, his voice cracking like dry obsidian. "What have you done? You opened it. A direct line to the shadow... to the demons. All manner of nasties are pouring through, and they are hungry. The vale... Aethelgard... everything we are building is screaming. You have to fix this. You have to figure out a way to fight your way back to that portal and seal it shut before the dark swallows us whole."

The weight of the mistake hangs in the damp cave air. The path backward is crawling with the very nightmares they unleashed. To save Aethelgard, and to save themselves, they must find a way to undo what has been opened.
