Is there any way Lillian can contact Hoho and ask for alchemy lessons?

That's probably going to be a bit hard thanks to our ([@TheWindel] and I) decision of temporarily reducing the Vassals influence on the story's course, after their presence caused undue/unexpected harm to the RP as a whole.

[@TheWindel] Well, if no-one else will be joining Miyu on her one way trip, there's no harm in going ahead and telling me the secret mystery they would have uncovered that Helena hinted at, right?

Your characters are supposed to discover the truth about the Nexus if they stay in. What Helena said that they would find outside is how the rest of the multiverse thinkis of the Nexus and, perhaps, some facts regarding the life in worlds outside of it (i.e.: the slice of life bits, showing how people live outside of the Nexus).

To answer your question, what people think outside of the Nexus is that it's a hell hole of war and violence that only the trully insane want to deal with. Also, there are some people outside that think that the Nexus maybe some kind of twisted experiemntation grounds.

These informations were supposed to compliment the fact that those who remained inside of the would find whether or not any of these claims are true. Nevertheless, as [@TheWindel] said, there's little use in splitting the RP if only one or two characters are leaving.
