The Guardian of the Library

Fae is bewildered after finding herself in an academy of Roblox entities. She befriends Timothy, the first entity to show kindness towards her, and spends more time with Figure. Although Rush is initially cold, he warms up to Fae over time, and Fae develops feelings for Figure while Rush falls for her. Their newfound friendship is tested when a human arrives and tries to harm the entities. Fae shows courage and risks her life to protect her friends.
