Q:How to construct a usable class in a method?

Trying to make a class based on user input, the problem I face is how to return created 'chosenHero' class? And so I could use that newly made class further on, adjusting properties and so on? I don't want to return a class from else

my Console App Game, GitHub project link is at the bottom.

Console.WriteLine("Would you like to play Mage, Warrior, Rogue or Warlock?");

private static object ChooseHero()
        {
            string answer = Console.ReadLine();

            //Formating answer to lower
            answer.ToLower();
            //Changing class name to Title Case.
            answer = CultureInfo.CurrentCulture.TextInfo.ToTitleCase(answer);

            if (answer == typeof(Mage).Name)
            {                
                Console.WriteLine("You have chosen a " + answer);                
                Mage chosenHero = new Mage();
                return chosenHero;
            }
            else if (answer == typeof(Warrior).Name)
            {               
                Console.WriteLine("You have chosen a " + answer);               
                Warrior chosenHero = new Warrior();
                return chosenHero;
            }
            else if (answer == typeof(Rogue).Name)
            {                
                Console.WriteLine("You have chosen a " + answer);                
                Rogue chosenHero = new Rogue();
                return chosenHero;
            }
            else if (answer == typeof(Warlock).Name)
            {                
                Console.WriteLine("You have chosen a " + answer);                
                Warlock chosenHero = new Warlock();
                return chosenHero;
            }
            else
            {
                Question($"Please try again... \nWould you like to play {nameof(Mage)}, {nameof(Warrior)}, {nameof(Rogue)} or {nameof(Warlock)}?");
                Warlock IdontWantThis= new Warlock();
                return IDontWantThis; //How to not return this part and Call ChooseHero method again?
            }                       
        }
