Paragon permission

Good evening
I am starting an RPG project and I would like to include the characters of PARAGON in this world, becoming primary and secondary characters, adding new animations and perhaps some modifications. And I would like to know how licensing on them would work. And as we have a question of advertising I would like to know if it is possible to use them in banners, posters and etc., if possible, I would like to know the restrictions, because I am also creating a visual identity, for a project of TCC taking advantage that I was to create the visual identity for the game. And I would like to use them on posters, special and limited cards baners.

In that I would like to know how to proceed.
