Wain left Twilight Steel's main base and climbed into one of the buildings where no one would disturb him. The organization members could not stop him as he was too fast. Also, there were no other evolved people on the base other than Hana and the man with the sword.
To them, Wain was an invincible and indestructible opponent. Wain could destroy Twilight Steel's main base if he wanted to, but Wain had no intention of doing so.
In his opinion, there was no point in destroying other organizations for no reason. They could have become part of the Last Light and increased the overall power of humanity.
After visiting the World of Darkness and fighting a few battles, Wain wondered what humanity was. He could not answer this question but realized that they had a unique position in this world.
