Celede Proclamation

The end of the Elvish Civil War, the Wood Elves are forced to accept the terms of peace offered them, but the Drow are defiant and face near annihilation. They are banished forevermore to the Under Dark.  When hostilities end, the High Elves arrange for a Gnome and Dwarf contingent to be sent to watch over the Drow.  The Dwarf tribe is eventually corrupted by their proximity, but the Gnomes remain pure and dedicated to their commission. This Proclamation sits poorly with the Wood Elves to this day.
