5 SIMPLE STATEMENTS ABOUT XREADU EXPLAINED

I desired to get every comic that may be related or that exists in a similar universe. Even non X-Gentlemen/mutant guides. 2nd query, are the rest of marvel outlined or exist in these guides such as avengers/spiderman and so on? In that case, are there textbooks for them that directly connects with property/powers/dawn/reign of x? Thank youI haven?
