The B-Trees forest is located west of Beerburgh and is in the southern region of the Badlands. It is so named for the dominant species of tree that forms the forest, known as the B-tree for its structure. In this dark and damp place, a plethora of fungi flourish and many a foul creature have made their home here. Such as the Torrent Leech, the Cawing Wumpus, and the Hyper Lynx. The forest is comprised mainly of B-trees, but there are also B+trees, R-trees, and even a mystical rarity known as the Binary search tree! It is well known that thousands of data banks are organised beneath the forest in a claustrophobic space moderated by an entity known as 'm.' The entity is said to frequently capture and store children. And that it's also fond of leaves; hence it chooses to operate beneath the forest.
It is sensible to avoid going anywhere near this deadly place! For much of its danger has been recorded from a fallen hero's diary, found at the forest perimeter.
