Elves were created during the Obsidian Wars by Obsidian Sorcerers as powerful chaotic leaders with very destructive tendencies. They were created as tools to dominate the natural world and the creatures within it. When the Obsidian cause failed, all of the creatures created by these Obsidian Sorcerers became leaderless, wandered away, and were mostly driven to extinction. Few survive today, and those that do find themselves hunted and hated.
In the intervening two hundred years since the Obsidian Wars, some elves, specifically those known as Vertas Elves, have reemerged with a new outlook on life, somehow they have turned over a new leaf, and found new purpose in life. These elves, while just as smart and powerful as their historic cousins, are masters of their own fate. While still often shunned or hated, they work to improve their own lives and come to peace with their warmongering past.
Outlanders that manifest in New Britannia, often take on a familiar human form, though many have noted their new Avatar manifestation differs significantly from their home world form. It is not uncommon to be taller, shorter, thinner or wider when an Outlander manifests in New Britannia. Even a change of gender is common when an Avatar manifests.
Rarely, very rarely, for reasons yet unknown, human Outlanders may manifest as Elves in New Britannia. So few such Outlanders exist, that any Elf claiming such heritage is likely to be disbelieved.
