SG10thAnniverse (or SG 10th Anniverse) is a fandom-created event leading up to and revolving around the tenth anniversary of the Sisters Grimm series and its celebratory special edition. It consists of themes and prompts to which the fandom responds with fanart and fanfiction. It is non-competitive and aims to foster a positive, celebratory environment.

Event Structure


The event is organized by four moderators: Kat, Lara, Ellie, and Edessa. Though all are active across all sites, they specialize in FanFiction, Wattpad, Tumblr, and deviantART, respectively.

Responses to the prompts are posted on Tumblr, deviantART, and They are tagged or labeled with "SG10thAnniverse" as well as the weekly theme tag, which allows the moderators to find all the entries. The mods then share or reblog entries to the SG10thAnniverse blog which acts as a hub and collection center for the entire event.

Some entries are also submitted straight to the blog via Tumblr's submissions box. 


The structure of the event is as follows: There are four weeks (planned so far), each associated with a different theme or prompt. These weeks were scheduled to fall evenly around August 1st, the 10th anniversary of the series. The themes are scheduled thusly:

Week 1: 7/20 - 7/25 

Theme: Selfie Week
Tag: #SGSelfieWeek

Week 2: 7/26 -8/1

Theme: Non-Romantic Pairings
Tag: #SGNoRomoWeek

Week 3: 8/2 - 8/8

Theme: Alternate Universe Week
Tag: #SGAUWeek

Week 4: 8/9 - 8/15

Theme: Romantic Pairings
Tag: #SGShipWeek

Late entries are allowed for any of the prompts. 

Due to the uncertain nature of the 10th anniversary of the series--specifically, little to no news about the books being released--the schedule is open to changing and expanding as the moderators get more information.
