Shard
From MYSTlore
A shard is an array of one or several game servers to support one instance of Uru Live. Shards do not communicate with each other; indeed, explorers end up on completely separate instances of ages, unable to see or send messages to each other.
[edit] Prologue
During Uru Live (2003)'s Prologue, three shards were created; first Atrus, then Katran, and finally, following the Clerical Error and the cancellation of Rehearsal, Achenar (using what used to be Rehearsal's hardware). Explorers frequently registered KI numbers on all three shards, and communicated outside the game to meet on one particular shard so they could actually meet each other in game.
[edit] Untìl Uru
In Untìl Uru, administrators unrelated to Cyan got to create their own shards and configure them to their liking, including such details as what areas of the City are accessible. The auth(entication) server, however, had remained Cyan's throughout. Particularly popular shards included Slackers and Tapestry.
In early 2006, Cyan created their own Untìl Uru shard, D'mala, as a precursor to their attempt at reviving Uru Live itself, which ultimately led to Myst Online: Uru Live.
Directories of shards can still be found: [1], [2].
[edit] Myst Online
In Myst Online: Uru Live, there are not multiple shards.
