An event organized to bring writers together, writing with a deadline (usually 3-6 weeks). Usually ficathons are theme or character based, 1000+ word stories where one writer requests a situation with 2-3 things they would like to see, and 2-3 things they would not like to see in the story written for them.

A ficathon is an organised fanfiction writing event. Such an event normally involves the writing of stories within a particular fandom. They will often all have a particular theme, such as being all about one character or pairing.
