But now back to my (Mornoni's) story. 
Omer lost his kingdom because of the secret combinations. 
3 And the Lord warned Omer in a dream that he should depart out of the land; wherefore Omer departed out of the land with his family, and traveled many days, and came over and passed by the hill of Shim, and came over by the place where the Nephites were destroyed, and from thence eastward, and came to a place which was called Ablom, by the seashore, and there he pitched his tent, and also his sons and his daughters, and all his household, save it were Jared and his family.
The Lord told Omer in a dream to leave, so he and his family traveled past the hill of Shim , and continued on to the east coast.
Jared was became king and gave his daughter to Akish. 
5 And it came to pass that Akish sought the life of his father-in-law; and he applied unto those whom he had sworn by the oath of the ancients, and they obtained the head of his father-in-law, as he sat upon his throne, giving audience to his people.
6 For so great had been the spreading of this wicked and secret society that it had corrupted the hearts of all the people; therefore Jared was murdered upon his throne, and Akish reigned in his stead.
After Akish married Jared's daughter, he became king by cutting off Jared's head (while his was stting on his throne speaking to his people), with a little help from his secret society friends.
King Akish then became jealous of his son, so he starved him to death in prison.
One of Akish's other sons (Nimrah) became angry at Akish for starving to death his brother.
So he and his friends left to hang out with Omer.
11 Now the people of Akish were desirous for gain, even as Akish was desirous for power; wherefore, the sons of Akish did offer them money, by which means they drew away the more part of the people after them.
Akish had other sons, who bought the hearts of the people.
12 And there began to be a war between the sons of Akish and Akish, which lasted for the space of many years, yea, unto the destruction of nearly all the people of the kingdom, yea, even all, save it were thirty souls, and they who fled with the house of Omer.
Eventually they went to war with their father, a war that lasted many years and killed everyone in the land except for thirty people, who fled to Omer's house.
After the war, Omer became king again.
He began to be old, had another son (Emer), whom he chose to replace him as king.
15 And after that he had anointed Emer to be king he saw peace in the land for the space of two years, and he died, having seen exceedingly many days, which were full of sorrow. And it came to pass that Emer did reign in his stead, and did fill the steps of his father.
Then he died.
16 And the Lord began again to take the curse from off the land, and the house of Emer did prosper exceedingly under the reign of Emer; and in the space of sixty and two years they had become exceedingly strong, insomuch that they became exceedingly rich --
After Emer became king, God stopped cursing the land, and everything was perfect for 62 years.
The people all became rich,
with silk, linen, gold, silver,.
and all kinds of farm animals -- cows, oxen, sheep, pigs, goats,
horses, donkeys, and elephants -- and even some cureloms and cumoms. 
20 And thus the Lord did pour out his blessings upon this land, which was choice above all other lands; and he commanded that whoso should possess the land should possess it unto the Lord, or they should be destroyed when they were ripened in iniquity; for upon such, saith the Lord: I will pour out the fulness of my wrath.
God blessed the land, which he liked better than all other lands on earth.
But he warned everyone that if they misbehave in some way, he'll murder them all.
22 And after he had anointed Coriantum to reign in his stead he lived four years, and he saw peace in the land; yea, and he even saw the Son of Righteousness, and did rejoice and glory in his day; and he died in peace.
Emer was a completely righteous king, who had many sons and daughters.
He chose one of his sons, Coriantum, to replace him as king.
Before he died, Emer even saw the Son of Righteousness. 
23 And it came to pass that Coriantum did walk in the steps of his father, and did build many mighty cities, and did administer that which was good unto his people in all his days. And it came to pass that he had no children even until he was exceedingly old.
Coriantum was a perfect king, just like his dad.
24 And it came to pass that his wife died, being an hundred and two years old. And it came to pass that Coriantum took to wife, in his old age, a young maid, and begat sons and daughters; wherefore he lived until he was an hundred and forty and two years old.
He lived to be 142 years old.
Coriantum's son Com became the next king.
26 And the people had spread again over all the face of the land, and there began again to be an exceedingly great wickedness upon the face of the land, and Heth began to embrace the secret plans again of old, to destroy his father.
Com reigned for 49 years and begat Heth, who became king by murdering his father after embracing the secret plans of old.
28 And there came prophets in the land again, crying repentance unto them -- that they must prepare the way of the Lord or there should come a curse upon the face of the land; yea, even there should be a great famine, in which they should be destroyed if they did not repent.
Prophets began to warn people that if they didn't repent, God would curse the land and kill them in a great famine.
29 But the people believed not the words of the prophets, but they cast them out; and some of them they cast into pits and left them to perish. And it came to pass that they did all these things according to the commandment of the king, Heth.
But the people didn't believe them.
They cast the prophets into pits and left to die, as they were told to do by King Heth.
30 And it came to pass that there began to be a great dearth upon the land, and the inhabitants began to be destroyed exceedingly fast because of the dearth, for there was no rain upon the face of the earth.
So God began to kill people with a drought.
31 And there came forth poisonous serpents also upon the face of the land, and did poison many people. And it came to pass that their flocks began to flee before the poisonous serpents, towards the land southward, which was called by the Nephites Zarahemla.
33 And it came to pass that the Lord did cause the serpents that they should pursue them no more, but that they should hedge up the way that the people could not pass, that whoso should attempt to pass might fall by the poisonous serpents.
As the people were dying exceedingly fast in the drought, God sent poisonous snakes to finish them off.
34 And it came to pass that the people did follow the course of the beasts, and did devour the carcasses of them which fell by the way, until they had devoured them all. Now when the people saw that they must perish they began to repent of their iniquities and cry unto the Lord.
35 And it came to pass that when they had humbled themselves sufficiently before the Lord he did send rain upon the face of the earth; and the people began to revive again, and there began to be fruit in the north countries, and in all the countries round about. And the Lord did show forth his power unto them in preserving them from famine.
The people who were dying from God's famine ate all of the people who were killed by God's poisonous snakes.
The people who survived God's famine and snakes knew that God would soon kill them too. So they cried to the Lord.
When they had humbled themselves sufficiently, God stopped killing them with the famine and poisonous snakes.
