Our champions fell upon Icecrown Citadel, at Arthas' hands. Among them were the likes of Tirion Fordring, Jaina Proudmoore, Garrosh Hellscream, Archdruid Lilliandra, and others. They have been risen as the Lich King's champions, enemies of the factions they once served. Our forces are crippled, and the Scourge's forces are bolstered every day. If we are to survive, we will have to stand and fight.
Rise of the Lich King is set during the tail-end of Wrath of the Lich King, in an apocalyptic setting where our champions fell and many, many of our soldiers died with them. Six factions scramble to save themselves in a dying world, cursed by the taint of Undeath and Frost. The Scourge spreads across Azeroth, fighting against the Argent Crusade, Ebon Blade, Kirin Tor, Horde, Alliance, and Scarlet Crusade.
The main prospect is providing interesting and fun mechanics, stories, and character progression (up until their imminent deaths, of course!). Players get to choose from seven factions, in which they each have their own unique and interesting goals and storylines. Now, let's get into the mechanics.
Whenever players do something meaningful, the Apocalypse Meter raises or lowers based on how things went. Once it reaches 100, it sets itself back to 15, and prompts a catastrophic event to happen, which can potentially affect everyone. In addition to this, if it stays above 60 for too long, a siege will occur on your faction's hub.
In our guild, we will have a unique roll system - when playing, you have four traits that alter your rolls, health, and other possible variables. One is based on your race, one is based on your class, and two are based on your character. You have a base Health of 30, a base Defense Value of 12, and a base Offense Value of 20. Whenever you attack, you roll out of your Offense Value, and subtract the target's Defense Value from the roll. The remaining total is the damage they take.
If I had 8 Health, and I had a Defensive Value of 12, and was rolled against for 16, I would take 4 damage, since 16-12 is 4 (you know that already). However, if the roll was 20, I would take 8, which would kill me.
You regenerate 3 Health every day, and can be healed for a maximum of 9 Health every day by healers. If anyone doesn't understand, explain what you don't understand and I'll explain it in more detail.
EDIT: Subject to change.
There are six playable factions, all with requirements and their own stories, hubs, and characters. There are also chances for more factions to be created, or for factions to be destroyed. There are currently The Scourge (Hard to get into), Ebon Blade, Kirin Tor, Argent Crusade, Alliance, and Horde.
