- Main article: Troubled Lands
The Troubled Lands is a frontier region located on the northern regions of Arrak. It is the third largest country on the continent. With its tough terrains and cold climate, civilisation is scarce with frontier towns scattered across the region. It is described as the "cold wild west".
The Troubled Lands is visited in the series from Sessions 32 to 39. The locations visited in the campaign are, in order of appearance, Spire of Winter (32-39), Hallow (33-34), Fenris' Lair (34-35), frost giant's land (38) and Monastery of Bahamut (38-39).
Unbroken Empire is a country located on the southern regions of Arrak, and it is the smallest country on the continent. Its inhabitants established the country by their own will, with no race superior to another. Slavery is outlawed within the Empire.
The Empire is led by a leader known as the Young Empress, described as a young (14 years old) god-emperor personality with powerful divine abilities. The Young Empress has issues with the deities, believing that they are the cause of the Lightfall. Thus, the only belief she thinks is worth following is one's self belief and that all people should work together. As Mark Hulmes commented, the Young Empress' philosophy is "very Jedi Order-esque [with] a bit of Buddhism" with goals of "perfecting the body, working together and everybody has to do their share." To enforce her belief, the Young Empress employs Paladin Knights to ensure that everybody works together. In turn, the Empire has no nobility, no upper class and no monetary system.
- Main article: Underdark
The Underdark is an underground super-region located underneath the continent of Arrak. There is no unified underground government since each individual city-state and region has a different form of rule. There are two known gateways into the Underdark. One is through the Temple of Tharizdun located in Whisper's Walk, Talis'Val. The other is via Aramount.
The Underdark is visited in the series from Sessions 20 to 25, and briefly mentioned in Session 40. The regions visited in the campaign are, in order of appearance, Garden of Stones (20-23) and Temple of Dah'Mir (23-25). The Aramount Mining Facility is mentioned in Session 40.
Planes of Existence
The Feywild is an magical forested plane parallel to the Surface. The plane is connected to Arrak via Longwood forest.
The spirit Cenaria roams the forest, which made an appearance in Session 6 to give the adventurers a mission to retrieve an object to revive Jiǔtóu. The Feywild appears later in Session 9 after the adventurers successfully completes the mission.
Arborea is a chaotic good-aligned plane of existence, stylised as a peaceful plane of natural beauty with a multitude of thriving environments. It is known to be spiritually connected to Arrak.
The Nine Hells of Baator
The Shadowfell is an underworld plane parallel to the Surface, ruled by the demon lord Orcus. The plane used to be connected to Arrak via a mausoleum located in Whisper's Walk, Talis'Val until it is destroyed in Session 18.
A demiplane version of the Shadowfell appears in Session 18, where Jonathan and the adventurers enter a sealed-off cathedral to seek and destroy the source that is disturbing the undead that threatened to overrun the streets of Talis'Val.
