The Battle of the Line
The term used to refer to the battle that occurred at the edge of the New City agains the forces of the Legion of the Light and the Horde of Kursk. This battle was fought just as the Light Wall retreated to the borders of the Old City and was necessary to give enough time for citizens within the New City to retreat into the Old City.
Technically the battle was a loss of for the Legion who could never stand against the amassed forces of the Kursk, and suffered massive causalities. However, the line did hold long enough for the majority of the citizens of the new city to escape.
Several groups of Adventurers also fought on the line, and those that survived (and some of those who did not) are now known as The Heroes of the Line amongst the general population.
