I admit only having glanced through the lunars book, not good for a GM Admitably.  But ya, it does seem Chimeraism is lessened.  There is some trouble in the wyld, but the Lunars have developed strength from it.   I  think as long as  they avoid the deep wyld they are safe, going too far in and  they face chimeraism.  And as you say that is more a story then mechanical issue- There is not even an example Chimera in the book.<br/><br/>Yes, Lillith is No cast.
