Aniimo First Sanctum Foray: clear First Spark

Aniimo First Sanctum Foray achievement: complete the opening story's First Spark Sanctum and use its final device to restore the Vein. Activating the outside entrance is not a clear. Steam's requirement does not name a four-chest condition.

Single source detailed route

1. Check that the entrance card says First Spark, then enter. The first entrance interaction can register travel before the next opens the challenge.
2. Awaken the supplied Emberpup at the opening statue and Twine with it. The trial supplies its own creature; preparing a separate field team is not the puzzle solution.
3. Use Fire Bolt to remove the wooden blockage and vines along the route. Follow the current skill prompt rather than a copied controller binding.
4. The authored chest route uses hanging vines, a fire beneath an ice-supported chest, a chimney fire and an explosive barrel. Inspect the local counter before leaving if you want those collecting detours.
5. Continue to the Sanctum Terminus, restore the Vein and inspect the first-clear result. Then check the platform achievement.

Clear and collecting are separate checks

The detailed route reports four optional chests. This draft does not claim they are required for the award, that every later trial uses Emberpup, or that registering an entrance completes a trial.

Single source: the detailed puzzle route is one authored walkthrough. General system references and a short trophy association do not independently verify every step. Current layout parity, missed-chest recovery and failed-unlock recovery remain UNSURE. No speed, difficulty or in-game-testing claim.
