'Belvaer, the commander here, has given some instructions for you, ${PLAYER}. Further up this tower lie horrors of Mordor which yearn to smother the light of the world beyond these fell eaves, corrupting Middle-earth as they have corrupted Mirkwood.
'If you are to march further, you do so in the face of great peril. If you feel able, you should scour this place for any clues or information that will be of use in our campaign against the Enemy, whether it be within these walls or abroad in the greater fight against the Enemy.
'I wish you luck, ${CLASS}! Please bring your findings to me -- but this is not a path that you should walk alone. Bring many strong friends with you upon this venture.'
The relics and tomes of the Necromancer can be found throughout Barad Guldur.
You should keep an eye out for any useful clues or information that will aid the efforts of the Malledhrim as you ascend Barad Guldur.
Anglú awaits you in Barad Guldur.
You should hasten back to Anglú and tell him of your findings throughout the tower.
