This is still in progress, but this is what I have so far.

The biggest thing is the event known as 'the Onslaught', which is basically when a horde of savages and monsters invade Omeria from across the southern seas.  The southern seas are dangerous, and you can only sail across them at certain periods, and when that period comes everyone from that southern continent sail northwards to Omeria and invade, which is what the Onslaught basically is.

Omeria itself is inhabited by four kingdoms of man, two groups of elves, and a race of demon-like beings known as Feyhorn.  The humans live in the north, the Feyhorn in the south, and the elves in the south.  And to put it simply: racism is very prominent and almost everyone hates outsiders.  It's very bitter and harsh in Omeria.

The Onslaught is underway and Omeria must prepare.  Because the Elves live in the south, they're the first line of defense.  Unfortunately, the elven races are divided between the Wood Elves and the Drow, and if they even hope to stand a chance they'll need to put aside their differences and work together - but that might not even be enough.

Meanwhile the humans are largely divided into the four kingdoms and fight a lot over petty things (like land, for one).  But one man has seen what will happen if Omeria falls and has managed to call together a peace council.  Unfortunately, one of the four kingdoms seeks to betray the others at this council, which will cause even more trouble.

The RP will follow two story lines that occur at the same time, and you may have a character in both storylines:

The North:  You'll be a human, a Feyhorn, or a City Elf (elves who live in human kingdoms, mostly the ghettos).  You'll be at this peace council, for whatever reason, and be part of the group that forms after it is attacked.  This storyline will follow these survivors as they attempt to form uneasy pacts between the four kingdoms and unite them to prepare for the Onslaught.  It's more or less politically-driven as we deal with the politics and tensions and racisms in Omeria.

The South:  You'll be a Wood Elf or Drow (they were all once High Elves but were divided and suffered a setback after the Arcane Wars physically divided them into the Wood and the Dark Elves (Drow)).  This story will follow the Elves as they are viciously attacked by the Onslaught and try to hold onto what little time they have left.

The two storylines will eventually draw closer and combine and result in an ultimate finale between the survivors and the Onslaught.
