Vina Villa is protected by a shifting labyrinth modeled after the labyrinth of Crete. It provides a safe route when no threat is detected, but may produce traps and minor Greek monsters when intruders are classified as dangerous.

Recognized members of the Vina family and their spouses possess a special bypass. Silk, the giant guardian spider, is part of the labyrinth's defenses.

During an earlier courtship encounter, Ryo used Axii to calm Silk and put her to sleep rather than harming her.
