Dust - Darkness
The explosion also opened up access to the Cirromon Caverns & the village of Mudpot below Aurora. In the caverns I found a new ability to crouch slide (just like metroid, you slowly get the skills to revisit areas & progress further) which is perfect for getting through tight spaces.
The flow of water has stopped to the village of Mudpot & I venture further deep into the caverns to find "The Lady" who is the next boss fight. She was overcome by Darkness & is now cured by getting her ass kicked by Dust.
With my new skill acquired, some armour upgrades & a ton of sidequests completed I can now venture to the Northern mountains & here starts Chapter 3 Love.
