Spies!

The Green Pool room was new and Elias didn't know about it, perhaps something from Unique Blueprint or Special Blueprint. Well, he doesn't know and doesn't care anymore.

The moment he fell asleep, Noble Isleen began working and digesting all information about herself. 

Both Elias and her might seem tireless in Cluster E but that was on the surface, especially in her case. She was the one doing all the chores. 

She run around the cluster wave, she produced goods, materials and metal for him to forge, she made the Blacksmith Workshop and keep improving it the moment she got a better one for him to busy himself, she was also the one making all the Bricks which he called Jade, and the thing was she has to alter the Brick Room for that to happen.
