Flamerule 8

Flamerule 8, 1369: (full moon)

    Stewart enchants two moon shaped buttons with continual light.  He
    gives them to Henkles and Elizabeth Rose.

    A mixed party of 8 demons and 20 barbarians attacks a caravan from
    Sundabar within view of the Everlund city walls just after dusk.
    The guard is quickly sent to help out (and 1 balista near the north
    edge of Little Turtle Hill is found to be in range). Several mages
    aid the battle, one of them by lighting up the sky in a 200yd.
    diameter area over the battle, which allows many to watch from the
    wall. The city guards manage to force the demons back into a dead
    magic region on Little Turtle's head and slay several of them
    before the remaining attackers retreat.
