Tanglewood

Tanglewood is a dark forest directly northeast of Goma Plateau, situated between it and the mountain that contains the Abandoned Mine. It has a negative reputation that comes about from being permeated by equally negative energy. It is said to transform at night, changing it into a wood that ensnares those brave - or foolish - enough to enter it at the dark. It, along with Goma Plateau before it and Abandoned Mine after it, comprises the first three-part introductory dungeon to Golden Sun: Dark Dawn.

Matthew, Karis, Isaac, and Garet must traverse the Tanglewood in order to reach Tyrell in the Abandoned Mine, and much is said about how it seems much more dangerous now than before. Various giant flowers stemming from the boss inside the mines obstruct their path, and after Garet demonstrates how to do so, Matthew uses the Fireball Psynergy to clear away several blooms and the roots they connect to.

It is one of the earliest revealed locations for Dark Dawn, having been seen as far back as the E3 2009 trailer.
