Even social interactions may be consented or denied, to prevent unwanted intrusive interactions with other players. This is to prevent "griefing" by other players. The game uses an extensive private TWiki project collaboration system to keep information for the player guilds and game staff. The game objects themselves are made with a unique set of tools called the StoryBuilder Toolkit. This has a browser navigation tree, called a "Tree of Woe" to let builders find existing objects, and other browser-based pop-up and command-line tools and scripts to edit and test new additions to the world. The core of the game is built upon LPC, but only the elite engineers of the game are allowed to modify such code.
