Oakstar

Spoilers ahead! Oakstar is an NPC. He is the leader of RoseClan and can be found in the Leader's Den.

Tutorial
As part of the tutorial, the protagonist will bring Oakstar a mouse that was obtained from the Hunting Grounds. He will then ask the protagonist's opinion on being a warrior. The protagonist's choice will not affect the general outcome of the game.

After the trial fight with a Dark Forest Soldier, Oakstar will proceed to tell the protagonist about a prophecy that tells of the army in the Dark Forest that is preparing an attack, and how the protagonist is destined to kill the leaders of the army before the attack can come to pass.

After Tutorial
The player may talk to Oakstar to spend their Daylight Hours on border patrol. The protagonist may specify up to 9 hours to spend on patrol, and will recieve 150 Gems for each hour spent (provided the protagonist actually has the amount of hours specified to spend on patrol).

After Level 4
The player may continue to spend Daylight Hours to patrol as before, but each Hour spent now earns 350 Gems.

After Snowflower's Message
Oakstar is wounded in the battle against BoulderClan and can be found in the Medicine Den, where he advises the protagonist to prepare for the night's visit to the Dark Forest, apparently unaware of Rockfoot's Apocalypse Crystal fragment. At this time, border patrols cannot be performed until after the completion of Level 6, at which time Oakstar will be standing in his den as per usual.

After Level 10
If the protagonist survives the battle against the BoulderClan warriors, they will notice Oakstar and Cloverstar facing each other in the middle of camp and will rush to aid him, only to be struck down by Cloverstar. Later, in the Medicine Den, it is revealed that Cloverstar had proceeded to kill Oakstar before leaving with the three prisoners.

After Post-Game Quest
Oakstar appears in StarClan to announce the end of the game. If the player did not enter the Bonus Code at the beginning of the game, Oakstar will reveal the bonus code to the player. If the bonus code was entered, Stonefall will appear and announce her decision to join BoulderClan. Oakstar will attempt to reason with Stonefall, but fails to change her mind. The game will then continue to proceed to the final hidden sequence.
