Sweetdust

Sweetbriar is a honey-gold tabby she-cat with short, curly fur and big yellow eyes.

She had been in love with Thunderpaw since they were kits and he saved her from a nasty fall. She was always very affectionate in the way she acted towards him, saving him fresh-kill and offering to do his apprentice duties, which he always refused. She grew frustrated when he remained oblivious to her feelings and told her that he thought of her as a sister.

In a bid to make Thunderpaw notice her, she mated with Turtlefern and had a single kit, Yellowkit. However, she was heartbroken when he showed only happiness for her, telling her that he always knew she was going to make a great mother.

Suspecting something going on between Thunderpaw and her brother Stormwave, she confronted her brother and attacked him when he insulted Thunderpaw. She miscalculated her jump and ended up falling down a waterfall to her death. When Stormwave returned to camp with her body, he said that he had found her body at the foot of the waterfall.

In the final battle, Sweetbriar comes face to face with Stormwave and reveals the truth of what happened, shocking Thunderpaw and Embernight. She also reveals herself to be the corpse that had stalked the questing cats throughout their journey and knew of Thunderwing and Stormfrost's relationship.

She apologizes for her actions to Stormwave, stating that she regrets that she didn't get to grow up with them. She also thanks him for protecting her by not telling the Clan what led to her death.

In the end, she chose to go to the Dark Forest rather than StarClan because she wished to accompany Yellowbriar as she grew up, which she wouldn't have the freedom to do if she were in StarClan.
