From EverQuest2.com:

Jesters, thieves, bards and fans of mischief are invited to enjoy the adventuring and new crafting festivities that surround Bristlebane Day! You never know what riddles, laughs and pranks are to be found during this enjoyable time of year.

Celebrators are present in every home city, and the oddest of objects have been spotted in Antonica, The Commonlands, Darklight Wood, Timorous Deep, Greater Faydark and Frostfang Sea! Be sure to keep your eyes peeled for special events, especially in Enchanted Lands, occurring only on the Highest of Silly Days, April 1st, 2011!

Bristlebane Day (April 1st) always brings out festivities and a bit of zanyness to EQ2. In past years, we’ve seen /cutemode (also try /cutemode 3 ) and in EQ1, turning everyone into wireframes. But this year, Bristlebane Day has put practicality in the place of tomfoolery.

Today, Bristlebane Day, a unique quest has appeared in the Enchanted Lands, offered by a Sphinx, which pays tribute to the father of Dungeons & Dragons — Gary Gygax.

The folks at ZAM were first to note that 2 of the 3 riddles given were also found in a FreeRealms quest.

Further exploration of the Enchanted Lands and other zones has revealed not only crafting tables from Frostfell, but also harvestable nodes for every recurring Norrath live event, including Nights of the Dead, Frostfell, Tinkerfest, and Erollisi Day.

If you have a desperate need for some event-specific craftables for your house or guild hall, don’t miss your opportunity!

While Norrathians will get to celebrate Bristlebane for an extended time (March 30 -> April 12th), there is a special quest only available on April 1st.
