Horizons: Do Dragons Have To Dress Up For Halloween?

Well, this one's for all those beta testers:

Cackles and whispers emanate from the shadows of Istaria, giving voice to rumors of endless night and mischief abroad. There is no telling when, or if, these murmurs will come true...
Please join us between 4-10PM PST this Friday October 31, 2003 on the Spirit shard for our Halloween event.

Thank You, Artifact Entertainment, Inc.

So, do the dragons really have to dress up?
