Riki is upset to discover a dead part of the forest. The Telethia has been draining the ether. We knuckle down to fight the three-headed dinobeast.
I used Shulk, Melia and Sharla. Presumably Melia was a good choice as we defeated the creature fairly smartly. I made copious use of Purge and Melia did whatever she does. We only managed one chain attack and it was fairly useless as I didn't have any topple arts. I thought we weren't going to need to entirely kill it when a cutscene triggered, but that turned out to be just to let it regenerate. Harsh.
After that I warped back to Raguel Bridge killed off the Hoxes (tougher than a Telethia, due to their numbers). Then asked Juju to move back to Colony 6 which opens up a whole new sub-quest - building the Colony.
I built a few things in the Colony, it's amazing what a couple of collectables and a bit of gold will do. The people all seem very happy with their new home in a bomb site.
Then we travel to Eryth Sea and some beautiful floating cities.
