Dialogue
 * "The Stone Summit are dangerously close to uncovering the Tome of the Rubicon. Inside is the true name of the Great Destroyer, the bane of the living and nemesis of the Great Dwarf himself.  If the seals that bind that book are dispelled and the true name spoken... well, let's just say there is no worse thing that could happen in this world.


 * I could use yer help gaining entry to Sorrow's Furnace and stopping the Summit from getting their hands on the Tome. Will you help me?"

Walkthrough
At one point in the quest, Alkar will ask your party to split up. One group will need to stay and defend him, while he recites a spell. The other group will need to find and bring back four Balthazate Crystals to complete the quest.

Priest Alkar is a powerful healer though and heals party members, so he's usually safe with 2 or even 1 party member staying with him to fight back occasional enemy partols. The rest of the party can go and get the crystals (which is the tougher part of the mission).
