Campaign of the Month: April 2011
This is a set of carved marble-like white stone blocks, from four to eight in
number. The blocks are set up in sequence surrounding the area to be locked. A command word
activates the wards, emanating invisible walls that prevent portals and gates of any kind from
opening within their boundaries. Spells involving planar travel are likewise disabled as if by a
zone of respite, though nothing prevents creatures from physically entering the warded area.
Each block is carved with two numbers, and is about one-foot wide on each side. The first tells
the user where in the sequence of wards to activate it, and the second is the number of blocks
in the set. Blocks from one set do not work with the blocks of another set, and if someone
attempts to use blocks from different sets, the magic is drained from all sets involved. The
placement of the blocks determines the overall shape and area of the ward; they can be
arranged up to 60 yards apart, in any pattern desired. The wall extends 60 yards above and
below ground while arcing over to create a dome.
Speaking the deactivation command while in the warded area dispels the wards permanently.
The wards also dissipate and fail a month after activation. Once dispelled, the blocks are no
