Okay, This is my first fanfic, please give some tips in the reviews!

Thunderclan

Bramblestar led his midnight patrol by the Sky Oak, heading for the Shadowclan border. Suddenly, he twitched his ears. There was an unfamiliar scent nearby, smelling of leaves and rain. He motioned to his patrol to stay quiet and track down this cat. He pushed through a bush, as quietly as he could, and just as he had thought, there was a rogue, sitting in a clearing, looking up at the sky. The rogue's ears twitched, and turned around. Bramblestar's heart sank. He was discovered. He eyed the rogue, a small, fluffy silver tabby and white she-cat with the biggest blue eyes he had ever seen. The rogue looked Firestar up and down warily, and then stopped, as if she recognized something. Then she got up, dipped her head slightly, and padded away into the ferns, leaving a mystified Bramblestar and his patrol standing in the moonlit clearing.

Shadowclan

Blackstar took his hunting patrol through the conifers, stopping every now and then to sniff the air more carefully. Suddenly he stopped dead, motioned to his patrol to do the same, and then slowly led them through the forest warily. After going over a ridge, he stopped. It was just as he thought. A small, fluffy, silver tabby and white she-cat with enormous blue eyes, smelling of leaves and rain, was just gazing up at the stars. Blackstar snarled, preparing to get this rogue out of his territory. The rogue suddenly took a step back, as if she didn't want to fight, dipped her head, and left, leaving Blackstar and his patrol standing in the moonlit clearing alone.

Riverclan

Mistystar was out for a walk. She couldn't sleep. When she got to the stream, she stopped and looked around warily. She could smell and sense another cat nearby. Carefully, she looked around, poking through the bushes, looking behind rocks, and stopping a bit once in a while to listen and sniff more carefully. Suddenly, she found a solid scent trail. Following it, she emerged in a small patch of marshy area occupied by a small, fluffy, silver tabby and white rogue she-cat with humongous blue eyes. Mistystar was torn between attacking her for intruding or questioning her. She opened her mouth to speak, but the rogue dipped her head at the Riverclan leader and walked away. It happened so fast that Mistystar still had her mouth open.

Windclan

Onestar was going for a midnight run with his deputy, Ashfoot. They were having the best time ever when they saw a cat on one of the hills. Ashfoot looked at him expectantly and he nodded. Thankful that the wind was blowing toward him, he and Ashfoot circled around until they covered both sides of the hill. The rogue, a fluffy silver tabby and white she-cat with giant eyes seemed unalarmed. Onestar looked closer and saw that the rogue's eyes were calm, even respectful. He was so surprised that he stopped. The rogue dipped her head to him and ran into the distance.

The Gathering

"We have two new apprentices, Seedpaw and Lilypaw." Bramblestar began the Gathering. "The prey is running well. There was also a sighting of a rogue in our territory. She ran off towards the Shadowclan border, Blackstar." He finished, gesturing that it was the Shadowclan leader's turn.

"We had a sighting too. It was a small, fluffy silver tabby-and-white she-cat with the biggest blue eyes I've seen in my life," described Blackstar. "Does that correctly describe the rogue sighted on your territory?"

"That's the one," Bramblestar confirmed.

"Riverclan has also had a rogue sighting, matching your description. But before she left, did she dip her head to you?" asked Mistystar.

All three leaders agreed.

"Okay, you've probably guessed by now, but we also had a rogue sighting a while ago, matching your description." Onestar mewed. "And yes, she dipped her head to me and Ashfoot while we were out running."

All of the leaders agreed that this was strange. The same rogue visited their territories and met with their leaders. And why did she dip her head before she left? The leaders of all four Clans agreed to discuss this again at the next Gathering. Little did they know that a certain silver she-cat was watching their entire meeting with narrowed eyes.
