and my version about the dwarves
SpoilerThe Great Destroyer has already been exiled to the depths. No one shall never speak of his name again, never set him loose from the depths and bring destruction.
Every dwarf must have heard of the legends of the Great Dwarf Guardian. many of the religious dwarves still believe before the appearance of humans, the Great Dwarf Guardian created the dwarven race at Anvil Rock. A part of the dwarves believed that there was a great battle between their god/gods/God and the evil forces. The discovery of a tome which was said to be the Tome of Rubicon, which was created by the Great Dwarf Guardian himself, in Sorrow Furnace will change the history of the myth of the dwarven race.
After stopping the Summit Dwarves’ attempt to obtain the prayer/inscriptions which could summon the Great Destroyer, High Priest Alkar led an excavation team to the Summit Hall, and tried to bring the relic of the dwarven race back home. After High Priest Alkar has cracked the codes of the prayer/inscriptions, he discovered that it did not only contain the battle between the dwarves and the evil forces sent by the Great Destroyer, it also told: The Great Destroyer promised to rise from the depths of the earth, conquering the whole world. The war between the Great Dwarf Guardian and the Great Destroyer will focus on the world. In the text of the prayer/inscriptions, there was no words on which side will win, but did point out that the dwarves will, because of this war, be changed/transformed forever. (well both is ok i think, we dont know the exact details only by looking at the text right now)
