Shadress has returned and she desires your destruction. At any point after you read this until Halloween is over, she may make an appearance in the Wasteland. There are a few things I can inform you of.

A system announcement will occur when she enters the Wasteland to alert everyone of her presence.

Shadress will tend to migrate towards neutral squares if any are present. This will allow more people to come to her to try and stop her rampage.

Shadress only cares about fighting the strongest of opponents. As such, she will only target those who are Avatars.

Shadress is a little weaker from her previous appearance, but will still be difficult to take down.

Those who take her down, i.e. land the final hit, will be rewarded with a couple goodies as well as the Shadress banner. Those who participate but don't take her down may receive an item or two as well.

If Shadress is on a square and is left alone for to long, she might start attacking of her own accord. Keep in mind though, she will only target those who are Avatars.

Good luck to all of you...
