"Previously under the control of Telflamm, Nyth once again considers itself part of Thesk and trades freely with its sister cities, including Telflamm.  The city received its name from the Will o' Wisplike creature that used to haunt the western edge of the Forest of Lethyr.  A cabal of wizards eradicated the nyth in a battle ofmutual destruction.  Since that time, wizards have been respected in Nyth, but are thought doomed to meet a bad end." 1
