Warrior Cats: The Blood Bind Book 1: Darkness's Kits

Harekit, though, could see through her lies. "You're lying!"

Bloodfrost yowled, "Don't you dare accuse my mate of lying!"

"But you two are in different clans!" Harekit mewed.

"We're both in Fangclan!" Bloodfrost growled.

"This.... this is wrong!" Harekit said. "How can you all be part of this... this clan of foxhearts!"

He scurried away, running as fast as his paws could carry him. Some of the Fangclan cats were looking mad, while others were surprised. Tigerstar did nothing though, despite the anger of betrayal by his own kin is his eyes. As Harekit disappeared into the tunnel to surface, Tigerstar faced his clan.

"Don't worry, he won't be able to resist the thirst for long." He said, trying to hide the bristling of his fur. "He'll be back."

Tortoisekit, Harekit, and Blackkit were always raised on the legend of the Fifth Moon, every fifth moon, instead of having a gathering, guards would be posted, patrols would cease, gatherings would be canceled, and cats of all statures, from apprentice to leader, would bundle up in the biggest den, pelts trembling in fear.

This is Tigerstar's curse upon the Clans.

One night Tortoisekit, Harekit, and Blackkit stray from Thunderclan camp, in search of this mysterious Tigerstar, stories told by the elders to keep kits away from the evil forces of the Dark Forest. A Tigerstar who had no kindness in his stone cold heart.

But after Tigerstar returned, more powerful and feared than ever, he instituted the Fifth Moon rule. Every Fifth Moon, Tigerstar would return to haunt the territories of all the clans, and if any cat was found outside their camp, they'd suffer a fate worse than anything; their bodies would be found in the morning, drained of all blood, jaws stuck in a horrifying yowl, and a distinctive bite in their necks.

"Starclan will fall, and the Dark Forest will rise again."
