Part 6/10:

A significant aspect of Morgoth's strategy involved the procreation of the Super Orcs. Although unable to create spirits outright, he sought to use the Maiar spirits encased within Orc bodies to reproduce. In theory, this could generate a vast number of powerful Orcs.

This “hereditary dilution” meant that their original power faded over successive generations.
