AU's and crossovers of all kinds are welcome. Any pairing you happen to ship is acceptable as well. Works over 1k words are preferred but if they are under that limit they are not necessarily excluded from entry. English is the preferred language but other languages are also acceptable. Perfect grammar is not required but any story included must have decent grammar and be in an easily readable format. Formats that I do not consider easily readable are works whose chapters are in one long paragraph and those |
