In his haste to save Faramir, Beregond has thrown open the Fen Hollen and makes for the House of the Stewards. In his wake, the enemies of Gondor descend on Rath Dínen, the Silent Street, all hoping to bring the rule of the Stewards to an end.
You should search Rath Dínen for signs of Beregond.
Rath Dínen, the Silent Street, is the final resting place for the Kings and Stewards of Gondor.
You should confront and defeat the members of the Withered Tree that have come to depose the Steward.
You should return the risen Kings and Stewards of Gondor to rest before pursuing the Gloom of Nurn.
You must defeat the Gloom of Nurn before he can claim the crown of the King for Gothmog.
