The word Sildor is no longer spoken in Alair; the land as it was when it was so named no longer exists. In the two years between late 1414 and the fall of Lomegor in 1416, Varkar and his minions systematically razed, destroyed and polluted the length and breadth of the elven lands. Using a combination of physical force, slave labour and dark magic, they reduced the once fair and peaceful land to a grey, choking wasteland, carpeted with ash, haunted by unquiet spirits, and home to no wholesome thing. The people of the Free Kingdoms refered to it as the Desolation.The Desolation was the source and home of the various breeds of the Curst.
After the fall of Varkar, and the return of the Elves (see Belamir), the Desolation shrank steadily until finally by the 1800s only a relatively small area remained between the Stormwall and the Tainted Forest
There are notable similarities between the Desolation and the Nhased Waste and it is possible that the dark magics used in their creation are related.
