Just for a test change your function login() below to function index() and see if it works!

Code:

class Account extends CI_Controller {

    function __construct()
    {
        parent::__construct();
        
    }

    function index() {

        $this->load->model('account_model');

        $query = $this->account_model->login();

        //$accountId = $this->account_model->account_info('id');
        
        if($query) {

            $session_data = array(

                'email'=>$this->input->post('email'),

                'accountId'=>$accountId->id,

                'is_logged_in'=>true

            );

            $this->session->set_userdata($session_data);

            //redirect('character');
            echo "oh yea!";

        } else {

            $data['error'] = "Bad login information supplied. <br />";

            $this->load->view('home',$data);

        }
        
        
    }
}
