Great Underground Lake — RoE

Great Underground Lake is an extra large underground map of 144 by 144 tiles, built for Restoration of Erathia and rated hard. Six players take part, all of them human-capable, split into three teams of two, with each player's faction chosen at random. Victory comes from defeating every enemy, and a player loses once all of their towns and heroes are gone. Water covers roughly a quarter of the surface, with grass making up most of the rest, alongside rock and dirt. The map is stocked with 18 towns, seven pre-placed heroes, and many guarded resources. Notable finds include the Crest of Valor, Equestrian's Gloves, and a Vial of Lifeblood, plus wandering elementals, a Beholder pair, and an Arch Mage.
