Lower Caves are the natural caverns and tunnels that don't reach all the way up to Lower Underrail nor all the way down to Deep Caverns.

Description

The only initially accessible part of caves is a nondescript cavernous area between Mushroom Cove and Junkyard. Consists of four zones; a waterfront tunnel, two cavernous areas with some ruined shacks and buildings to the west and Siphoner Pools. One more small area becomes accessible during Abram's quest Free Maura. Some azuridae and rathounds can be found lurking in the waterfront tunnel between Junkyard and Mushroom Cove. Further to west, hostile junkyard thugs can be found in a ruined shack and wounded Cliff in a ruined building further to south.

Once the player gets access to TNT Charges, cave passages blocked by rocks can be opened. This opens many new cave exploration possibilities, mainly Hathor caves east of Crossroad Watch. The cave tunnels between Mushroom Cove and Junkyard may contain entrances to random dungeons.
