Old Ties

After Kahn and the group returned to No Man's Land, he had 4 objectives in mind. 

One was the temporary asylum he desperately needed. 

Two, he wanted to check up on people he cared about that he had to leave behind in the Rakos Empire. 

He sent Ronin who could turn into a spirit form to cross the border undetected and complete the other two objectives. 

Third objective was to contact Tobias and get all the resources they had amassed such as SS Rank Mana Cores and Ores since the time they left. 

Kahn and the group didn't need money… they needed these resources to level up and become stronger. 

Since they were forced to leave in a hurry and didn't want to leave a trace behind, Kahn didn't go back to the Oakenshield company building and bring all the resources they had siphoned in the name of managing Throk's company.
