Welcome Akela 
 
If I can give you a suggestion, you could use 2 nations at once for a game. So if you are ganged up by the AIs you can "help yourself with the other hand", and it will become less frustrating to be attacked 

 It also removes the problem of inadvertently clicking the "End turn" button 
 
Marverni is a bit difficult to play for beginners, imho, as Astral magic, and expecially the communions part, is hard even just to learn and a lot more to master. You could consider starting with something a bit more straightforward - Abysia is great for that, but you could have fun with Agartha, Ulm, Yomi... Those aren't definitively powerhouses, but are simpler to play and you will start to have the impression that everything you research really 
improves your army 
 
Hope to see you on the board often!
