Improved Grand Master Disciplines
As you rise through the higher levels of Kai Grand Mastery, you will find that your Disciplines will steadily improve. For example, if you possess the Discipline of Grand Nexus when you reach the Grand Master rank of Grand Thane, you will be able to pass freely through Shadow Gates and explore the nether realms of Aon and the Daziarn Plane.
The nature of these additional improvements and how they affect your Grand Master Disciplines will be noted in the Improved Grand Master Disciplines section of future Lone Wolf books.
