I am still not 100% convinced that Zera is an illusion casted by Mavis... Usually in FT universe... when one loses a battle or fell unconcious, their magic ceases... and Zera should've vanished... I know shes technically not there... so her appearance makes no difference...

I just don't know why shes a unique one that no one can see, and has its own consciousness... Is it just an imagination from Mavis? And at the end, why is it that the only time the others can sense her?
