Its main landmarks include the Myconid colony at Ebonlake Grotto, the Arcane Tower, Selûnite Outpost and Grymforge.

What is in the Underdark?
The region is a compact slice of the broader fictional Underdark, not a tour of the entire setting. Its named areas include a settlement, ruins, a tower, an outpost, a village and a forge. The bg3.wiki Underdark page also lists the Wilderness and Shadow-Cursed Lands as adjacent regions.
Ebonlake Grotto
In the north, Ebonlake Grotto is a Myconid-colony hub. Sovereign Spaw and Glut are among its notable residents; traders Blurg and Derryth Bonecloak are there, as is Omeluum. Thulla is another named character associated with the grotto.

How does the Underdark fit into Act One?
The Underdark is one of the possible regions to explore during Act One, with multiple ways in and quests that connect to the wider journey. Its compact scope matters: the game depicts only a portion of the larger fictional Underdark.
