Unlocking the Quest 
1.Prerequisites: You need to complete the previous quest, likely part of the Archon Quest line in Mondstadt. This quest becomes available at an Adventure Rank around 18-20, but check your quest log for exact requirements.
2.Starting the Quest: The quest might start by talking to Kaeya in Mondstadt or directly at the entrance of the Temple of the Wolf.
Quest Walkthrough
1.Meeting Kaeya: Begin by meeting Kaeya at the designated location, probably near or inside the Temple of the Wolf.
2.Entering the Temple: Follow the quest marker to enter the temple. Kaeya might join you as a trial character or an active party member for this quest.
3.Exploring the Temple: Navigate through the temple. You'll encounter puzzles, typically involving Anemo (wind) elements or Cryo interactions due to Kaeya's abilities.
4.Combat and Puzzles: Use Kaeya's Cryo skills to freeze enemies or create paths over water surfaces. There might be mechanisms or torches that require Cryo to activate or extinguish.
5.Deep Within the Temple: Continue deeper into the temple, solving puzzles which might include lighting torches in a specific order, using wind currents to move platforms, or defeating guardians like Ruin Guards or hilichurls.
6.Boss or Key Event: There could be a confrontation or a significant event, like encountering a mini-boss or finding Stormterror's crystal, which you might need to destroy.
7.Concluding the Quest: After overcoming the temple's challenges, there might be a cutscene or a dialogue where you learn more about the lore or receive crucial information. Exit the temple or teleport out.
Quest Rewards
•Adventure Experience: A decent amount for quest completion.
•Primogems: Likely around 40-60 for completing significant quests.
•Mora: Standard quest reward amount.
•Character Experience Materials: Like Hero's Wit.
•Kaeya: If not already unlocked, this quest might be a way to unlock him or understand his abilities better.
Quest Tips 
•Elemental Synergy: Make sure to have a party that can trigger elemental reactions. Kaeya's Cryo with an Electro or Pyro character can cause powerful reactions.
•Use Kaeya: Since he's central to this quest, use his abilities to your advantage, especially for Cryo puzzles or combat.
•Exploration: The temple might have hidden chests or secrets. Explore thoroughly.
•Puzzle Patience: If a puzzle seems tough, take a moment to observe your surroundings for clues or mechanisms that might not be immediately obvious.
•Save Often: Although Genshin Impact autosaves, manually saving before critical points can be helpful.
