Located in central Ehb, the Eastern Swamp is a large estuary at the northernmost end of the Bay of Ehb, where runoff from the Green Range flows down the mountains and into the sea. The wetlands are infested by swarms of dangerous insects and monstrous amphibians known as 'manglers'; there are even reports of swamp trolls and swamp witches lurking deep within the heart of this region. To the north lies the Dark Forest.
An Azunite temple located here was desecrated by a wakening evil during the Seck Resurgence, causing the dead to rise from their tombs. A hero purified the temple with a blessed icon given to him by a dying scholar.
The Goblins who ambushed the Grand Mage Merik dwelt within the swamp, using a large tree to hide the entrance to their secret laboratory. It was here that they took the Staff of Stars after stealing it, and it was here that a farmer from the west retrieved it in their quest to save Ehb.
The nature mage, Andiemus. found himself stranded in the swamp until the same party seeking Merik's staff found him, and recruited him to their cause. The friendly witch named Verma also lived somewhere in the Eastern Swamp, brewing potions and selling them to passers-by.
There was also, near a health shrine, a strange chunk of land that descended into a smelly dungeon, which shortly rose back up into the swamp.
