After living in the twolegplace as an aggressive rogue for years, he shows up on SkyClan's borders and is vouched for by his brother, Cloverjaw. He
reunited with Silversmoke, refueling a long-standing rivalry from before the creation of the clans. Not long after Slate joins, he participates in a
battle against WindClan and witnesses Blazestar lose a life.
Slate aids a small patrol in
driving out a fox from SkyClan's territory, though the tip of his right ear is torn off. A murderous rogue named Kuiper is
put on trial, where Slate and several others speak out against his heinous crimes.
Weeks after multiple cats have been taken from SkyClan's territory by twolegs,
Silversmoke and Slate get into a heated argument and near-altercation before being interrupted by a stray dog. Not long after,
Slate himself is trapped by twolegs and taken away to the shelter.
After a moon spent in the shelter, Slate and the other SkyClanners are freed and
return to camp. In the following meeting, Blazestar
apprentices Howlpaw to Slate and promotes him to Lead Warrior.
An attack from WindClan occurs at random, and
Slate battles a warrior named Cygnetstare. They engage in a proper scuffle, and although WindClan technically wins the fight, Slate has nearly torn her throat out.
Slate gets into an
argument with Bobbie and Sweetybee when Fantastream brings toy mice into camp. He
voices his concerns about the way that SkyClan handles joiners, especially kittypet joiners, in a council meeting. Unexpectedly, and begrudgingly,
Slate takes on Cherrypaw as his new apprentice.
Yellowcough plagues the clans, and when Blazestar makes a call for volunteers to embark on a dangerous journey to find the cure,
Slate offers himself in a perhaps surprising turn of events.
Through all of the dangerous and treacherous events that face the journeying cats, Slate perseveres. However, he finds himself truly feeling hopeless during the
cave-in event, where he has a panic attack and is talked through it by the ShadowClan medicine cat apprentice, Magpiepaw.
Slate
saves a WindClan apprentice from a badger attack, teaming up with Figfeather in the process. He also happens upon the scene of
Little Wolf's death, where he promptly scolds his apprentice Cherrypaw for venturing off on her own in the first place.
The journeying group, almost home, is ambushed by dogs and
Slate freezes out of fear right before being knocked into reality by Orangeblossom and Milkpaw. Utterly flustered from nearly being mauled,
Slate urged the group to continue on despite there being injured party members. Much to his dismay, Slate and Figfeather are the only SkyClanners who
return home on time. Shortly after,
Slate breaks the news to Blazestar that his former mate and the mother of his kits, Little Wolf, had been killed on the journey.
Slate
realizes, after a period of denial, that he still has romantic feelings for Orangeblossom.
