The Jungle at the End of Forever
Bristle stands at one side of the crystal, dark magic ready at hand, while Caleb goes to the other and draws a blade. Voh'ren, Hester, and Firea stand ready, weapons and magic prepared.
The lance of enervating power hits the crystal a moment before the first drops of blood from Caleb's hand. Darkness twines through the crystalline structure, then begins to spread out through the web of silver threads, tarnishing them in a steady progression outwards. Hester feels a strange sort of nausea come over here, an illness that doesn't seem rooted in her body.
Then the blood touches it, and crimson-gold light dances through the crystal's facets, following the darkness out and overtaking it as they spread through the silver strands. Light and shadow play and dance among the web, forming intricate patterns and almost-shapes before -

Hester feels pain wash over her, but it feels somehow good, cleansing - like the ache after a day of satisfying labor, or a well-deserved slap. And then the pain fades, not nearly as bad as she might have feared, and with it the sense of unease or longing that she was feeling, the draw towards the crystal vanishing.
The crystal shatters. Whisper staggers out, melting away at the extremities, looking shocked, only for Voh'ren's axe to take her in the neck and slice clean through. No blood comes forth, only mist, and her body dissolves into mist with a soft sighing sound.
The crystal destroyed, tremors begin running through the demiplane around you, reality itself warping as the structural keystone of the pocket dimension breaks. The walls unravel, revealing darkness blacker than the space between stars. It's a race back up to the upper level, where tears are appearing in empty space, blackness showing through and spreading as you dive through the entryway and -
Awaken, near Zedoran's lair in the Fangwood, in the very instant you left at. The skeletal dragon and bear made it through, even, and all the party members are intact. The charm-sight lenses show no signs of infection on any of you. As far as can be determined, you successfully purged Whisper's presence from the world, sending her on at last to face judgment for her many crimes.
