This just in from the official DDO site:

Hello Citizens. I am Veheer F'nord, Augur of the Twelve. I bring ill tidings to you this day.

This is definitely no time to party now that Sir Lawrence has gone missing. According to my research, it seems the devils of Shavarath have made up their mind to perform a counter-strike in retaliation of our thwarting their General. I will be making an appearance tonight around the same time that the graffiti first appeared, to try and get a better grasp of what clues may be derived from their markings. For devils are lawful, not chaotic like foul demons. Their regimented nature may prove to be their undoing. My initial findings seem to indicate that whatever it is the devils are planning, it will be revealed to us for days to come, and it seems to favor the time range of fifteen minutes prior to the 22nd hour (9:45 PM EST, -5 GMT). Perhaps they thought going off the hour would fool us and catch us unawares. However, while their mischief has already begun, I fear that the ultimate culmination of their evil, based on the infernal writings, is next Sar (Saturday), and more than likely at that same time. This will be when they try to twist the knife in our weak spot. Anyone who spots anything amiss throughout this week should continue to give us reports from the field, so we can work together to try and stop them!

Those wishing to avoid the dangers of the Marketplace may seek out a member of the Twelve, Zoth Naylte. He will usher citizens to other wards of the city safely by way of teleport. Citizens should not travel alone as they navigate the marketplace streets, for the dangers of these Shavarath devils is not to be under estimated. I will bring more information when I can.
