Note that there are four Ancient Dwarven Chests, scattered about the mines, containing the four missing stanzas. If you follow this wallkthrough, you'll find the stanzas in the indicated chests. If you deviate, one to all of the stanzas will be in different chests, because the stanzas are obtained in order, regardless of the order in which the chests are opened. I.E. The Silver Stanza will be in the first chest opened, and the Mythril Stanza in the last.

Head down the stairs from the Kalrathia teleporter and continue down the following southeastern stairway, passing by the fountain on the south side. Enter the building where young Lord Kalrathia and his traitorous advisor Kynos can be found and you will first encounter Historian Leontia at her desk. Speak to her (choosing the first response) and agree to find the missing stanzas to initiate this quest.

Teleport from the Kalrathia teleporter to the Upper Mines of Kaderak (West) teleporter, or just arrive there during the normal primary quest activities. Head south across the walkway above the tracks, then continue east along the ledge. Head north back across the next walkway over the tracks, then continue east along the ledge of the opposite side. Head north into the rectangular room and open the Ancient Dwarven Chest, which contains some treasure and the Silver Stanza.

First head east, then turn north up the stairs and go through the double doors. Continue north to the corner, then turn east and head down to the next corner. Be very careful of the large aggregation of barrels, many of which are explosive, at that intersection. Use a ranged character to destroy them from a safe distance, or you may end up resurrecting one or more or your characters. Continue south through the triple doorway and down the stairs. Head on across the narrow bridge over the chasm and activate the final switch, if doing this during the course of the primary quest, else head east through the doorway into the large room and exit through the door on the opposite side. Head east just a little bit further, then turn south and go through the double doorway into the room, containing a table and chairs and some beds. Continue through the double doorway to the west into a smaller version of the prior room. Activate the switch between the second and third beds to the south to open a secret area. Head on into the small room to the south and get some treasure plus the Gold Stanza from the Ancient Dwarven Chest.

Teleport from the Kalrathia teleporter to the Lower Mines of Kaderak teleporter. Check your compass and you'll note two pathways emanating to the south.

Once all four stanzas have been obtained, teleport back to Kalrathia and head down the stairs and continue down the following southeastern stairway, passing by the fountain on the south side.

She'll bestow some gold upon your party and they'll receive the Chant of Prosperity for returning the first three stanzas, plus the Greater Chant of Prosperity for returning the fourth stanza, which completes this quest.
