Spalvi Stout-heart has decided that there is no other way, and if you wish to find Bingo again you will need to follow the Iron Garrison into Moria.
'I had hoped we might not have to follow the Longbeards into Moria, ${PLAYER}. I may not be a Dourhand any longer, but the old resentments are not so easily swept away. Well, if they do not greet me with steel I will repay them with kindness, and not in kind!
'During our time here, I have learned that the Iron Garrison travelled south-east to the ruins of Echad Dúnann, outside the Hollin Gate. You should speak to the dwarves there and see if they have gained access to Khazad-dûm! If they already have done so, or once they do, I will meet up with you inside the entrance to the great dwarf-kingdom!'
Spalvi has agreed to meet you just inside the entrance to the dwarf-kingdom of Moria once the Iron Garrison has opened the Doors of Durin at the Hollin Gate.
Spalvi Stout-heart is in Durin's Threshold, just inside the western entrance to Moria.
Spalvi has decided that following the Iron Garrison into Moria is your best hope of finding Bingo Boffin.
