Ether Seals are magical seals that are placed by the Mursaat in key places (gateways, doors, etc.) to help guard them. Ether Seals themselves are usually guarded by Mursaat or Jade Armor/Jade Bows. When found on a gateway or door, destroying the Seal will open the way through. They are also sometimes found on Mursaat Towers, which (when powered by a Seal) constantly drain energy, deal damage, and strip enchantments inside the glowing ring around them. Destroying the Seal in this case will remove the tower's effects.
