Orem is the home of the elves.
In Orem, all knowledge is supreme importance, including dates of birth. As such, one's age is a closely guarded secret from most. The elves of Orem are unusually shortlived due to their internal politics resulting in an unusually high number of murders and suicides. With no magic they live as long as any other race; a long-lived denizen of Orem might live to 100 years.
"The rituals of Orem take as much as they give." (Baduruu)
