A tile is a landscape texture of 128 or 256 pixels. Diffuse tiles must have identical pixels on the left/right columns and top/bottom row, which will be drawn ingame as a single pixel column and row respectively; this is necessary for proper texture interpolation.

Tile Bank (also .bank)

The tile bank is a description of a set of Tiles, defining which tiles are used, and how they are mixed using alpha tiles. A tile bank defines the style of an Ecosystem. It is created using the Tile Editor tool. The build pipeline builds this into the Small Bank, a simplified version of the bank, and the Far Bank, the long distance version of the bank.


An ecosystem is defined as a style of landscape. It consists of one Tile Bank and a collection of Ligo Bricks that are painted on using the ecosystem's tilebank. Ecosystems are used by Continents.

Continent (also .land)

A continent is any physically and visibly separated area. Only one ecosystem can be used by a continent. No two ecosystems and thus no two continents can be visible at the same time. A continent is assembled using ligo bricks with World Editor.

Ligo Block/Brick (also .zone)

A ligo brick is a piece of landscape that is 160x160 meters large, or is a multiple of this for special zones. Modeled in 3ds Max using Quad Patches. They can be textured using the patch painter, making use of one tile bank. They can be assembled into a larger Continent using World Editor.

Ligo Material (Block/Brick)

A set of ligo bricks with matching edges that can be placed next to each other in all positions.

Ligo Transition (Block/Brick)

One or more sets of a specific number of ligo bricks which are used to transition between different ligo materials.


A primitive is a large xml file which contains point located entities in a continent. It is used for placing trees during gamedata build, for environment fx and sound client side, and for placing zones and ai scripts server-side. It is created using World Editor.


A shape is just a 3d model.

Georges Sheets

Georges Sheets, or just Georges, or Sheets, are the names for an XML based file format used for describing static leveldesign content.


A creature is a type of Georges sheets that defines the static parameters of an ingame entity. This is used for base player race stats, npc's, mobs, as well as dynamically spawned static scenery.

Static Item (or .sitem)

A static item sheet defines the parameters of an item that can be owned by a player, or can be sold by a merchant. It is used for all items in the inventory, including equipment and materials, as well as any pseudo-equippable item, such as facial texture variations (tattoos), hair styles, and underwear.

Game Item

A game item is an instance of a sitem, with dynamic parameter values that may depend on which materials or other sitems it was made from.

Static Brick (or .sbrick)

A static brick sheet ... does stuff. It can be 'learned' by a player by an NPC trough missions, or at trainer NPCs by using Skill Points.

Static Phrase (or .sphrase)

A static phrase sheet defines a template combination of sbricks. It can be learned by a player at trainer NPCs by using Skill Points for the sbricks in the sphrase that the player does not yet know.


Sabrina is the system that ties the sphrases and sbricks together. (or something like that.)


RAID, short for Realtime Army Invasion Deployment, is a marketing term. It usually refers to the protocol used to transfer entities from the frontend server to the client. It can also refer to a proprietary set of ai scripts used in 2004 and 2005 to manage enemy mobs in PvE invasion events.
