There was something bad going on and Alfin could feel it. As for what it was, he didn't know at the moment, but he knew that it would be problematic, to say the least.
'Can't let this old man leave my side.' He thought while he overlooked the explored map of the cave in front of him.
Where his target will surface its head, Alfin wasn't sure. He just knew that it was going to do it soon and inside the Decidue cave.
'The same cave was built by machine overlords of old and if Alfin's memory serves him right, they were still running independently in the deepest reaches of this cave.
'There should be some connection between that lab and these overlords. This is why that lab is showing signs of surfacing in this area.'
Even if it was a mobile underground lab, it still needed resources and energy to maintain its functions. And what better place to acquire these, if not the Decidue.
