The world of Lineage II is a war-torn land spanning two continents, where trust and betrayal clash as three kingdoms vie for power. The young king Raoul has successfully quenched a civil war and established the newest kingdom, Aden. Elmore, the military superpower located in the northern part of the continent, boasts that it is a direct descendent of ancient Elmoreden kingdom. Gracia, located across the ocean on the west, is currently embroiled in a chaotic battle among blood relatives trying to take over the throne. These kingdoms share a delicate balance of power; however, within each kingdom they are vulnerable to internal strife, as each manor has strong desire for self-rule.

You have been thrown into this chaos. However, unlike the ordinary people who pray each day for safety, you have the power to protect yourself. In Lineage II, developing a character is not an end in itself. Rather, it is your instrument to obtain the power to enforce your will in this world. Seize your destiny! Your own hand will write the history of this world.

Chronicle 4: Scions of Destiny is an expansion that adds 800 megabytes of new content and features to Lineage II: The Chaotic Chronicle, the market's premier player-versus-player (PvP) massively multiplayer online PC game. The expansion is one of the largest updates released in the MMO industry and is free to current Lineage II subscribers.

Chronicle 4 adds several new major features to Lineage II, including the opening of the high-level hunting areas Rune and Godard, a new castle in Godard which players can attempt to seize, the nearly invincible fire dragon Valakas, and a fishing system that provides players with a profitable non-combat activity.

Also, Chronicle 4 rolls-out several features for high-level players including a third class transfer where players who reach level 76 may obtain more powerful and useful skills. Also introduced is a "hero and noblesse system" where level-75 players can compete in the Grand Olympiad, an extreme PvP challenge in which the winner is designated the rank of "hero" and receives new powerful weapons and a special heroic aura that everyone can see.
