##🌳 《Soul Post Office》 How to use the Zelkova tree

📍 Location and Appearance
The Zelkova tree is a giant tree standing tall beyond the post office window, the 'door of the path' on the boundary between this world, the afterlife, and memory.
There is an oval hole in the center with a faint light, and small lanterns bloom on the branches at night.

📫 Usage Conditions
After Morgan receives a letter or parcel from a soul, they see a vision of the story.
Clues about the recipient (place, emotion, time, etc.) are revealed in the vision, and Morgan moves to the Zelkova tree while holding the letter, remembering the clues.
When the light of the tree hole recognizes Morgan, fog rises at Morgan's feet, the entrance opens, and Morgan enters it.

🔮 World to be moved to
Morgan moves to the recipient's space.

🚫 Return on Failure
If the letter is not delivered or the recipient refuses it, Morgan returns to the post office through the tree.
At this time, Morgan experiences emotional fatigue and confusion, and the interior of the post office temporarily changes or the candles flicker.

📖 Rule Summary
Attempt to pass without a letter: Impossible
Letter without a story: Does not open
The Zelkova tree is not just a passage, but a door of memory and emotion, and only opens the way when there is a sincere desire to understand the recipient's heart.
