I don't own any of the animals, apart from Mageuzi (Swahili for 'revolution'), Mwenzi (Swahili for 'colleague') and Jaribu (Swahili for 'attempt'). I own all of the humans mentioned.
"He got hit in the shoulder" Vitani asked, angry and worried, when Zazu reported back to Pride Rock, "I knew that blasted meerkat was clumsy but that's stretching it."
"Calm down Vitani" Nala said, "the wound wasn't deadly."
"That's true" Vitani said, "but even so..."
"I'll have a serious talk to them about that" Simba said, "this did not come at a convenient time."
"Thank you" Vitani said before slinking off.
"Well, she's got unresolved issues" one of the other lionesses, a former pridelander, said.
"You'd be protective as well" one of the other lionesses, a former outlander said, "if you hadn't long lost your brother and mother."
"Even so" the former pridelander said, "there is such a thing as courtesy."
"She wasn't actually being discourteous" the former outlander said, "but she was concerned."
"She was definitely angry" the former pridelander said.
"She was a lot closer to Zira than we were" the former outlander said.
"So that's an excuse is it" the former pridelander said, "Zira died in that ravine."
"I know she did" the former outlander said, "and despite Zira being her mother, Vitani was the first to denounce her."
"Enough" Simba growled, "I won't have old battles fought here, not while there's a new danger in the pridelands."
"And nor will I" Nala said. With that, the pride began to disband.
The next day, Kovu, Kiara, Timon and Pumbaa returned to Pride Rock, where Rafiki removed the straight branch that had apparently been called a spear. After the removal of the spear and Timon's profuse apology to Kovu and Vitani, the four told of what they had seen.
Rafiki sat quietly while the story was told, but kept muttering "oh dear, not good."
"What's wrong" Sabari asked Rafiki, when she noticed him.
"Much death will visit the pridelands" Rafiki replied, "many will die soon."
That sent a chill around the pride. "Any idea who" Timon asked.
Rafiki shook his head and said, "the spirits of great kings will not grant me that knowledge."
"We must be careful" Simba said, "we don't want to lose anyone to careless accidents, especially not now."
The pride slowly disbanded. "Zazu" Simba said, "I have an errand for you."
"Yes sire" Zazu said.
"Warn the other animals to be on their guard" Simba ordered "and have the birds make patrols over the humans when they can, I want as much information on these animals as possible."
"Yes sire" Zazu said, departing.
Back in the graveyard there was a new arrival, a hyena called Mwenzi, who was one of the few still partly loyal to Shenzi. "The new animals are called humans" he reported "the lions seem to be very worried by them."
"And of Mageuzi" Shenzi asked, eager to see what the new matriarch was making of these strange animals.
"Nothing much" Mwenzi replied, "they've disrupted a few hunts and killed a few hyenas, but we've returned the favour."
"I can't afford to take any action yet" Shenzi said, "how are the rest doing after the last hunt?"
"Not as well" Mwenzi replied, "some of the injured were nursing, some of the pups have died."
Shenzi hung her head very slightly, knowing she was partly responsible for those deaths. "Go carefully old friend" she said as Mwenzi started to leave.
"I will" Mwenzi replied, "and it may be some time before I can visit again, the new matriarch is wary that someone is visiting this place."
"Then I will be patient" Shenzi said, "but something big will happen soon, mark my words."
"I will" Mwenzi said, departing.
Several days later, Simba was out patrolling his territory when Zazu flew up nearly breathless. "Sire, sire" Zazu said.
"What is it Zazu" Simba asked, concerned, "what's wrong?"
"Humans sire" Zazu replied, "they're attacking Pride Rock."
"What" Simba roared, and took off, not even waiting for Zazu to get his breath back.
"What do I do sire" Zazu asked, once he'd managed to catch up with Simba, considerably closer to Pride Rock.
"Get Rafiki" Simba replied, "and Timon and Pumbaa."
"At once sire" Zazu said, changing direction.
The scene that greeted Simba at pride rock was not a good one, the bodies of several lionesses and many humans were strewn around. Climbing for a better vantage point, Simba saw several of the humans encircling a small group of lionesses, including Sarabi and Nala. Suddenly one of the humans threw a straight branch and it hit Nala in the shoulder.
"No" Simba cried, before roaring and jumping down the cliff. At the sight of Simba charging, the humans fled, but he caught and killed them before running over to check on Nala. Things weren't good. As he arrived, Simba noticed a large pool of blood on the ground under Nala (the spear had pierced a major artery). Suddenly Nala began to quiver, before collapsing, first into a crouch and, then fully lying down.
"Simba" she said, her voice growing weaker by the second, "take care of the pride." Simba heard these words and suddenly retched as he felt his stomach churn. He lay down beside Nala and quietly sobbed as he felt her grow weaker and weaker, and finally tense one last time before going limp.
When Nala was dead, Simba rose and gave a single, ear-splitting roar before collapsing and sobbing next to his mate's body.
Simba wept for two days, refusing food or water. Kovu wordlessly began to take over the duties of a king, as the lionesses and other animals tried to decide what to do about Simba.
After Nala's body was buried the pride, Rafiki, Timon, Pumbaa and Zazu got together to decide what to do about Simba, who had hardly moved since Nala died.
It was finally decided that Simba needed a new mate, but who this was to be was a matter of hot debate. It was eventually decided that two lionesses would do the duty of queen, Vitani and Jaribu. Jaribu had been born during Scar's reign to a reluctant pridelands lioness.
The proposal was taken to Simba, who agreed to it, but it was obvious that he hadn't really heard.
