Havoc Week has been celebrated for at least ten years now, both here on LJ and various other sites.
The themes for each day are as follows:
23 April -- Havoc Day
24 April -- Strip Havoc Naked Day
25 April -- Spying on Havoc Day
26 April -- Lunchtime Havoc Day
27 April -- Spank Havoc Day
28 April -- Havoc Gets Lucky Day
29 April -- Molest Sleeping Havoc Day
30 April -- Sexy Outfit Havoc Day
That is a whole lot of HavocXRoy to enjoy! :D
Any fanworks you create for Havoc Week we would love to have crossposted to celebrate_fma, which is a comm (still active) for enjoying FMA fanworks about holidays, celebrations, and fandom events.
We are one week out from Havoc Week, so ladies and gentlemen, get those fanworks ready!! \o/
