Assiti Shards series

The Assiti Shards series is a fictional universe invented by Eric Flint. It is a shared universe open to authors of many calibre levels, concerning several alternate history worlds, related to a prime timeline. The defining characteristic of the fictional universe is the existence of the "Assiti Shards effect", and the impact that strikes by Assiti Shards have on characters in the stories. The series is rather large and expansive, having started publication in 2000, and as of 2008^[update], consisting of 15 print books, and 21 e-magazine anthologies, in two different published timelines of the same multiverse (only one work is in the second timeline).

The Assiti Shards work by displacing bits of the world into other times and places, exchanging it with that which was there. These "shards", according to the fictional universe backstory, are waste byproduct of artworks created by the sophisticated and curious alien race known as the Assiti. The various stories involve shards striking the Earth and timeshifting characters into different periods and places.

The first literary work in this fictional universe was 1632 (pub. 2000) by Eric Flint. This work led to a series of works that branched off this, into the Ring of Fire series (aka 1632 series). Most of the works in this fictional universe fall within this particular timeline. This timeline involves the displacement and exchange of the late 1990s mining town of Grantville, West Virginia with a piece of 1630s medieval southern Germany (in Thuringia).

Although 1632 was written as a stand-alone novel in 2000, Flint had planned several other universes using the Assiti Shards story premise. However, the sensation and interest engendered by the 1632 novel's publication subsequently caused the other works to be delayed while the 1632 series was developed.
