Welt: What's the matter, do you need something from me? 
Me: Can you give me info about the Astral Express 
Welt: You're new here, I can't give you any kind of information yet 
Me: It'll be by force then
Welt: You better not do anything risky, if you don't want to die, please back up 
Me: Are you that powerful?
Welt: In another universe I was the herrscher of reason, and most of my power remains 
Me: Okay I won't bother you more
