The Wetlands is a large, wet zone below Stonewrought Dam and north of Loch Modan, covered with small rivers, lakes, and ponds. Bordered on three sides by mountains, the Wetlands are open to the ocean to the west. Adventurers seeking a route to the Wetlands must either come through sieged Dun Algaz from Loch Modan or cross the damaged Thandol Span from Arathi Highlands. The northern slopes of the Wetlands are generally classed within the Khaz Mountains.

The Wetlands is a vast, cold swamp. Mists cloak the ground, and the overcast sky makes the land a uniform gray. Many Ironforge strongholds once stood in this region, but war has reduced them to rubble. Wild creatures, murlocs, and renegade orcs now control the land. Menethil Harbor, a city on the west coast, is the Alliance's only presence in this dreary region.

The Wetlands have been the site of many a battle through the times. Nestled among the Khaz Mountains and open to the ocean as it is, it is a prime location for invading forces. It was historically part of the original dwarven kingdom while the three tribes were united, but after the War of the Three Hammers, it fell under control of the Wildhammer Clan. The Dark Irons invaded Grim Batol and almost succeeded in taking full control of it, but were driven back at the last minute. During the Second War, the bastion finally fell prey to the invading orcs, most notably by those of the Dragonmaw Clan.

Although the orcs took possession of Grim Batol for a time, they were subject to the wrath of the red dragonflight who, when freed of their enslavement from the orcs, destroyed their bases and burned their catapults, killing orcs en masse. The orcs who survived the onslaught fled south to the mountains, where they live to this day. Horde and Scourge forces devastated the Wetlands in the Second and Third Wars, forcing the Ironforge dwarves to retreat to Loch Modan and Dun Morogh.

Grim Batol is now under the control of the red dragonflight, who fiercely defend their lair from outsiders. Alliance forces have since established Menethil Harbor, but the area is still wild and untamed. The dwarves and allied humans built the port city on an island in Baradin Bay, which they named after King Terenas Menethil II Menethil Harbor. The Wetlands is a buffer zone between inhabited Khaz Modan and Scourge-infested Lordaeron.
