Timer

What it is
The timer shows the voyagers how much time they have left to complete a voyage before the shadow hour begins. The timer is set for about 36 hours in the first realm. It varies from realm to realm.

In the beginning of a voyage, the timer resembles a black sun.

As the voyage goes on, the black slowly disappears to mark the passage of time.

The less time remains, the more shadow soldiers will appear. As it gets close to completely disappearing the sections that were gone start glowing red/purple. Once it fully disappears, the timer remainder glows white, and the Shadow Hour begins. Once the Shadow Boss appears, he blocks the view of the timer.

Significance
The timer is often used to show how much time has passed from one event/another. For example, where Kodya was while Tori, Gyrus, and Sylvia were trying to find Gyrus's "ship".

It's also used to build suspense and add to the theme of time.
