Notes on using the Underland Map of Thay:

- This map functions just like the Overland map of Thay, however there are no inaccessible locations within this map.

- Areas with a double-red line around them are static areas (ones that are not generated by the underland travel system). These are mainly segments of Undrek'Thoz; however they also include points of interest, such as areas of adventure or non-drow towns nearby the realm of Undrek'Thoz.
