List of Terminology

This is a list of terminology that is used in Log Horizon.

Adventurers
Players of the game Elder Tale are known as Adventurers.

Catastrophe
The Catastrophe, also known as the Apocalypse and the May Revolution, was an event that occurred on May 3, 2018 at the release of the Homesteading the Noosphere expansion pack in Japan. All players logged into the game at that moment were suddenly transported into the game of Elder Tale -- or, at least, a world much like it.

Classes
Officially known as "occupations," classes are chosen by an Adventurer when they begin playing the game. Upon selecting a class, an Adventurer cannot change it without creating a new character. There are four groups of classes: Warrior, Weapon-based, Healer and Mage. These four types are similar to the Tank/Healer/Damage per second (DPS) roles commonly found in most MMORPGs. In Elder Tale, though, the DPS roles are split into two groups of base classes that differentiate between physical and magical damage. Each server also has its own special classes that replace one of the normal ones.

Expansion Packs
Like most MMORPGs, Elder Tale releases new expansion packs every couple of years. The latest one, Homesteading the Noosphere, resulted in the transportation of over 700,000 players into the world of the game.

Health Points
Health Points (HP), sometimes referred to as "Hit Points", are a standard in most games as a way of gauging how much damage a person can withstand. Once this parameter reaches zero, the character is either rendered incapacitated or dead, depending on the rules of the game. One's HP in Elder Tale are level-based and skill-based, and can healed either by another player or with a health potion. When an Adventurer levels up, his or her Health Points will increase.

The People of the Land also have Health Points, but theirs will/won't increase depending on what the system purposed them to do.

Mana Points
Mana Points (MP) is a power level which a player uses to cast spells or activate combat skills and abilities in battle. It can restored by potions when players use it up in combat. However, MP-recovery potions are known to be weak, causing spells or abilities that increase one's MP recovery rate to be very popular in parties.

People of the Land
Officially known as "Landers," People of the Land were originally NPCs when Elder Tale was a game.

Servers
There are twelve playable servers in Elder Tale: North America, South and Central America (which curiously contains the southern half the U.S.), Western Europe, Scandinavia, Russia, Africa, Middle East, India, China, Japan, Korea, Southeast Asia, and Oceania.

It is later discovered that there is a hidden test server, Mare Tranquillitatis, where Adventurers go to when they die; this server is located on the Moon.

Snowfell
A winter festival that takes place in December, it correlates to Christmas in the real world.

Solo Players
Solo Players (ソロプレイヤー, Soro Pureiyā?) are those who play alone and don't form any lasting Party with other players in Elder Tale. Benefits include higher experience and undivided loot, but drawbacks include more danger to the individual if attacked with ailments like paralysis or by overwhelming odds. Before the Apocalypse, most solo players set out as mercenaries for other Guilds, with Shiroe as a prime example. Since then, most players have prefer joining guilds than soloing due to the dangers of their new world.
