Cradle of Life

The Cradle of Life is a treasure chest found at the end of the fourth level of the Stronghold of Security. Once opened, the portal near the entrance can be used to reach the end of the level. A player can only open it only once, and only if he or she has set their recovery questions. When opened, the player will get to choose one of two styles of boots and the ability to use the Stomp emote.

Trivia
The "cradle of life" could be a reference to the movie "Lara Croft Tomb Raider: The Cradle of Life"

Each level of the stronghold represents a certain theme. The final theme being life at the end of a hard journey.
