Morathi rules Ghrond without compromise and does not tolerate interference from outside. It is one thing for the Hag Sorceress to support Malekith in his rule but quite another for her to accept it herself. The Witch King tolerates his mother's small rebellion so long as her tithes are promptly delivered and generous in scope -- and generous they are, for the mines beneath Ghrond have ever been rich in gold, silver and gemstones of all kinds. Even after thousands of years, there remains sufficient wealth buried beneath Ghrond to buy the loyalty of every Elf in Naggaroth.[1a]
