Mourclesis

"And everything it touched was corrupted; and everything it touched was made barren; and everything it touched was subsumed. The old world was gone; only the mist remained."
—Chronicle of the Black Sword, Chapter One

(Mourclesis is a bastardization of 'mourir', French for 'to die', and Epiclesis, the part of a Christian worship service when the Holy Spirit is invoked in the symbolic bread and wine.)
