History
Helmed Horrors are over 5,000 years old. Both Netheril and Imaskar are well known to use helmed horrors.

Creation
The process of creating helmed horrors was something of a bad secret for many years. While unknown to the magical community at large, a great number of clerics of Bane, liches and evil wizards knew well how to create these constructs. It is now uncommon knowledge. A powerful spellcaster, with knowledge of both construct creation and arms and armor creation is needed, and a special workroom, along with the spells needed for the ritual.
