The whole area of Alabaster Fortress became covered in ashen haze that inhibited vision and hearing. The adventurers below the walls could not hear the commands of those atop the walls. The hearing of everyone affected by the haze is limited to someone about two meters away from them.
The sight is inhibited by the haze while the groaning of hundreds of people echoing in the haze inhibits the hearing. The adventurers and soldiers below the wall could only fend for themselves. The odd thing is that there were no enemies attacking them just reduced vision and disoriented hearing.
All the groaning suddenly stopped and a bone chilling laugh echoed all throughout the haze. The soldiers and adventurers who heard this laugh all ha a tingle in their spine. Along with the tingle in the spine is a sharp reduction in stats.
[All your stats have been reduced by 20%. If you die, you have an 80% chance to become an undead.]
