Shadows of Undrentide wasn't designed for a gamer wanting to continue his adventures from the original module, which isn't typical for an expansion. It was designed for us to create a new character as the level cap is still set at twenty.

This is disappointing, as one wants to continue the life of his original character and find out how the people he encountered, fared. It also makes you feel like the original character created has gone to waste. Well, please don't make the mistake of deleting your original character. You should save him for the next upcoming Bioware expansion.
