Imperial Academy. The heart of chaos

I returned to the academy, but I have little time. Two months later, a wedding with an unwanted man should take place. Lost memories are gradually returning, but I feel that I miss something important. Grandmother makes global plans, in which for some reason I assign a central role. The patron saint of fire wants to be near. And I have to master chaos, and this is difficult more than ever. But I will definitely deal with everything. And with his own strength, and with a new threat, and with patrons. And I will definitely find out where I had so much pain, which or about who I forgot about.
1) What happened to the memory of paradise and patrons? Will the memories return?
2) What is chaos?
3) What happened to the elements?
4) Will the gods return?
5) And can Alda destroy his belt of fidelity?)
