You have found Bingo, but he lost something of his own while he was away: his memory!
'You know, there is something we might try. Do you remember the page of manuscript that Willem found? It is mostly dry now, and nearly legible. Perhaps if you were to show it to Bingo it might provide just the reminder our author needs in order to regain his missing memory!
'I say it is worth the attempt, ${PLAYER}!'
Bingo Boffin is at the Fanged Pit.
Spalvi has given you the page of manuscript that Willem Whisker found within Moria, and believes that if you show it to Bingo it might help him regain his memory.
Spalvi gave you a number of leads to follow that might help you collect the lost pages of Bingo's manuscript:
'Merrevail in the Fanged Pit might have some pages. Orcs and Warg-riders cover great distances throughout Zelem-melek, and they might have found some pages. A war council was formed in Anazârmekhem, in the Flaming Deeps, and its leaders might have uncovered some pages. Dwarves in the Twenty-first Hall that see a lot of traffic for their services, such as vault-keepers or bards, might also have come into possession of pages.'
Spalvi said he would meet you at the Twenty-first Hall after you followed all of his leads.
Bingo is in the Twenty-first Hall, ready to read the manuscript you assembled.
Bingo is reading through his own manuscript... but he doesn't know it!
Bingo is in the Twenty-first Hall of Moria.
Bingo has finished reading his manuscript, and you should speak with him to see if it helped him regain his memory.
Spalvi and Willem Whisker are in the Twenty-first Hall, waiting to see if Bingo has regained his memories.
