Rumbling Cave is an area in the south central section of the Needle Hills region. It is home to one of the unobtanium shards which are needed to located the Well of Souls. It has multiple entrances, connecting it to the Upper and Lower River Banks.

Able Ryder entered the cave to retrieve the unobtanium shard that lay within. Upon retrieving it, the cave began to collapse, leaving only one path to the north open. Ryder escaped just in time, and the last entrance collapsed behind him as he left.
