Some lore:
The general idea is that the character lives in the world with the separation into 4 nations with each representing their element. The world itself is set in this steampunk setting, where each nations are responsible for maintaining central "CORE" mechanism, which supposedly is super important makes the world turn round. So each nation has their specialty in terms of working on this mechanism.
The character here is named Sinek and she is a part of air nation. They can fly and do diagnostics of the entire mechanism and can do quick fixes, due to their high mobility. They live in the mountainous part of the world. The props provided are some of their equipment. The tree is the tree of wisdom. It is somewhat ritualistic, in a sense that the dying members of the community designate a "wisdom" to another younger member of their choice, when they turn a specific age. And through that our protagonist finds out that this core mechanism is not what it seems and she embarks on the adventure to uncover the truth about it all.
