Legend
Perhaps a renegade dwarf from the city was secretly a cleric of Orcus and used the sewers as a hideout, or as a place to research new methods of creating, strengthening or commanding undead.
Perhaps he carved his journal on stone tablets instead of on perishable paper or parchment, and hid them in a secret location in the sewer.
Perhaps the tablets were uncovered by the cave-in, but most were destroyed. The tablets that survived are now lying in pieces near the fire beetles' lair.
Perhaps the wizard saw the pieces, but either did not recognise them as dwarven writing, or did not realise that they were anything more than broken stone.
If the PC finds the pieces of the tablets, puts them together and gets someone to translate them, perhaps the tablets could give information about the city, reveal the location of a hidden cache of useful items left by the dwarven cleric of Orcus, or provide other campaign hooks.
