Alright, since you only got gen1 chars I reset the role on Cayn and you can now set it as your new main char.
Quick explanation of the mechanic for main/alt chars:
All characters created while your main char is alive (as in not deleted) will automatically be tagged as alt chars and can never become main chars.
To create a new main char you will need to delete your current main, create a new character and set that as your new main.
Have fun!
