To quote the home page

The universe – all that we know, all that exists – is dying. It is time for a new universe to be born.

In a place far removed from our own mortality, spirits and souls do battle to determine which ethos will midwife the birth of the new creation. This place is known by many names but those there refer to it as The Nexus.

Nexus War is a browser-based mbumively-multiplayer online roleplaying game wherein characters and their factions vie for control over territory and power throughout several planes of existence.

As characters grow in experience and power, they discover that their every ethical action weighs against their soul. Those who persevere and are good may eventually ascend into angelhood while those who make evil their lot may descend, becoming a twisted member of the demonic horde. However, free-will is the dominant ethos, so many choose neither path, opting to study deeper, unaligned magicks and ways of combat.

It’s PVP, There are a lot of powers, and factions raiding each other is a big part of the game.
