The Dimension of Doors

Like the astral plane, the Dimension of Doors is a place where mystics travel to various worlds and dimensions. Called the Nexus in some circles, this plane is a vast city of doors built on an outcropping of rock that may be approached either astrally (using the Astral Form power) or using Dimensional Movement. The sky within the city is a magnificent starscape shining various bright colors and patterns, though it has also appeared as a dull gray sky, blank and empty, in times of turmoil along the Cosmic Coil. Though the dimension is basically one sprawling city, there are few who call it home. Some lone wardens or guards maintain outposts, but, for the most part, the city is only temporarily populated by the various travelers accessing the doors.
The identity of the builders of the Dimension of Doors is lost to history, but the Master Mage Ios is known for having discovered and refurbished much of the realm. She wove the spells that maintain many of the gates and paths here and established the Door Wardens to watch over them. The Door Wardens are an order of mystics recruited from across the planes to uphold the sacred duty to safeguard the dimension and keep the keys that open the many doors. They aid and guide travelers through the dimension, particularly assisting those who are lost.
Navigating the Dimension of Doors is more difficult than one might imagine. Multiple doors can lead to any given dimension, and therein lies the problem. Instead of attuning oneself to a dimension, a traveler needs to know the right door, and if the wrong door is chosen, they could end up in a dark dimension, a void, or some hellish netherworld. So, how does one choose a door properly? The first way is a simple mystic attunement. Any character with Mystic Awareness can make an attempt to navigate the Dimension of Doors.
Another way to choose the right door is with knowledge of arcane lore. Unlike the attunement method, the traveler can get help from thing like maps and signposts, both of which offer assistance to find the right door.
