After King Greytooth seized control of the Flaming Spire, Spakorth fears what may have become of his brethren in the Oath-taker's Horn.
'At my request, Gimli has offered to escort me to Zôreth's chambers in the heights of the Spire.
'We shall force Váskmun to hear my counsel, even if he heeds not a single word of it. Indeed, the Stout-axes may still be free of the tyrants of Mordor, but Váskmun has become one of them, whether he believes it or not.
'I trust Gimli's axe shall keep me from harm, but I would ask that you seek Sversting, Dréri, Náth, and Freki as we storm the Spire. If they have not already realized the King's folly, I would have you convince them to abandon the search for the dwarf-rings and seek refuge among Durin's Folk as Gimli has proposed.
'As for Eitur... he may stand in our way, but he is a dwarf of words and little else! He has always sought to please those in power, and I think his loyalty now as false as it has ever been. If he stands in the way of the King, he must be defeated or exposed as the coward he is!
'Go, ${PLAYER}! Gimli and I shall follow you into the Spire!'
Sversting can likely be found about the forges on the lowest level of the Oath-taker's Horn.
Spakorth has asked you to seek his brethren with the Oath-taker's Horn. Since you are entering at the lowest level of the Spire, you should first seek Sversting and see if he might be convinced to abandon Váskmun Greytooth's quest for the dwarf-rings.
Dréri, Náth, and Freki can likely be found on the central level of the Oath-taker's Horn amidst the Firehorn barracks.
Sversting proved fiercely loyal to King Greytooth's quest and fought you valiantly. You should now seek Dréri, Náth, and Freki in the Firehorn barracks above.
Eitur can likely be found in Zôreth's chambers on the highest level of the Oath-taker's Horn.
You have found all of Spakorth's brethren except for Eitur. You should now seek him and defeat him if need be.
Spakorth can be found in the doorway to Zôreth's chambers alongside Gimli.
You have found all of Spakorth's brethren, but unfortunately Sversting and Eitur proved unwilling to abandon their King's quest. You should now speak to Spakorth in the Oath-breaker's Horn.
