Thanks for the chapter. You could watch the “ghostbusters” movies to get more ideas and inspiration. About the “ectoplasm problem” you could make Damien use his mental abilities and the Ghost Zone to organize his mind and do a command that automatically make his subconcious destroy the ectoplasm that goes off him. Also, when Damien claims the Ghost Zone, remember that people could use the energy of his dimension if they use magic or have powers about energy, so that he can block or permite their use. That way, he would not be unaware or you could just make it that they are unable to use his dimension, even if he isn’t denying them.
