The Builders were the mysterious fourth race of the Kencyrath, sent ahead to prepare each threshold world in turn so that when the previous world had to be abandoned, important things such as the Kencyr temples were ready for use.
Against the native power of the Anarchies, the Chief Builder had a talisman or device; the object known to the Kencyrath as the Kenthiar, but known to the Grindarks as the Men-thari. It was supposed to be a parting payment to the Grindarks along with the Anarchies themselves and the city the Builders constructed there.
One day the Grindarks found the Builders all gone, with the work unfinished. The Men-thari, the Kenthiar, was lying where the Chief Builder left it the night before. The Grindarks thought to take it, but instead it cut the head off the first Grindark to put it on.
Jame finds the city in the Anarchies in Dark of the Moon and a skeleton of a Builder; she speculates that the rathorns may have used the power of the imu circle to scream the city to pieces, with the builders still in it.
The Builders appear to be short in stature (barely to Jame's waist), with long-fingered hands and large eye sockets.

Then suppose the rathorns came back, maybe through these tunnels, and… and used the imus to scream the city to pieces, with the Builders still in it. I found a skeleton in that house I explored. It wasn't human. There could have been more there, hidden in corners and holes all over the city, where they crawled trying to escape.' "
