Sava

Sava is a game created by the drow. Resembling chess, it involves the moving and capture of pieces that represent soldiers on a battlefield. While the gameplay itself is merely hinted at in the several books it is mentioned in, again, a chess-like game can be inferred. This is the game Lolth and Eilistraee are seen playing in the Lady Penitent series, with the board representing the entire plane of existence.

The Pieces
The pieces in sava are labeled Warrior, Slave, Priest(ess) and Mage. Certain adaptations are allowed, expecially in a deity-played game. In the case of the Lolth versus Eilistraee match, specific pieces known as Champions and Mothers were put into play. The Mother piece represented each goddess specifically in these matches, and it was implied that capturing this piece not only ended the game, but the losing goddess would be slain and absorbed by the winner. In the case of Lolth, her Champion was the demi-god Selvetarm, who was later slain.

Gameplay
No specific mention of how the game itself is played. It is mentioned that each player can move a single piece per turn, and each piece has a set axis of motion, much like a bishop in chess can only move diagonally.

The Random Dice
In order to inject a bit of chaos into their game, the drow have a pair of six-sided dice ready for a sava game. Each player is allowed a single roll of the dice in a game. Nothing cited actually explains what the different rolls mean or cause, but it was taken as an extremely good result when Lolth rolled double ones in her match against Eilistraee, at least the result was good for Lolth. Eilistraee's earlier roll of double ones also caused a great strategic victory for Eilistraee, which turned out to be planned by Lolth all along.
