Halloween 2007 was a Guild Wars in-game event, to celebrate the annual return of the Mad King, who comes to the world of Guild Wars every year, on October 31st.
 Halloween 2007 Event: The Mad King Returns (Again)
- When sunlight wanes to shadow
- And mists fill nights once clear
- 'Tis time to think of monarchs
- Who visit once a year.
- Hail, Thorn, the king demented,
- Whose laughter fills the air
- Where cunning gifts are given
- With wit and deadly flair!
- And as the season passes
- Remember what you've seen
- In Lion's Arch and Kamadan
- On this good Halloween.
 The Mad King is coming!
The Mad King is coming! The Mad King is coming! That's right—he's baaack! Joined by his entourage of ghoulish cohorts, Mad King Thorn will entertain visitors with his cornucopia of mini-games and new jokes, and will reward participants with a variety of special Halloween items!
Mark your calendars for the event, which begins on Friday, October 26th, and runs until 11:59 p.m. Pacific time on October 31st. During the event, adventurers will notice that the Tyrian port of Lion's Arch and the Elonian port of Kamadan shine with an otherworldly glory befitting a king, especially a mad one! Once again, the maniacal monarch has decided to grace both cities with his ghastly presence and will reward his loyal subjects (and party participants) with prizes and a special Halloween gift. Or is that gifts?
So come along and spend a little time with Thorn—his sense of humor is guaranteed to slay you! But while his wicked jokes may lead to your untimely demise, your inventory will be all the richer with small mementos and a unique prize that he generously provides you.
