Helm Mechanicum

A Helm Mechanicus is a type of mind impulse technology used by lesser Nobles to pilot the smallest class of Imperial Knight known as Knights Armiger. A Helm Mechanicus is similar in function to the more advanced Throne Mechanicum required to pilot the larger variants of Knight.

Armigers are usually piloted by the lesser Nobles of each Knight household; those whose lineage is not directly linked to the lords of the court. In taking on the role of Armiger pilot, they fulfil a solemn vow, donning the fabled Helm Mechanicus with which the spirit of the man or woman and their great war machine is linked into a single entity.

The Helm is linked by invisible chains of data to the Throne Mechanicum of their Noble liege's larger Knight armour -- chains so strong they can be plucked as the strings of a puppet by the Noble within the Throne Mechanicum in times of great need. This forces the Armiger pilots to carry out the actions directed by their liege, as the higher-ranking Noble takes over control of his vassal Knights' basic functions.
