Lunar Rift

Lunar Rifts are mysterious sites found on the Hidden Vale and Novia continents of New Britannia that allow people to teleport to several different scenes.

Lore

 * Each lunar rift is a pocket of long-range teleportational energy in the center of a circle of standing stones. As the moon phases advance, the teleport destination changes. The locations of lunar rifts and their destinations are Blood River, Solace Bridge, Highvale, Brookside, Owl's Head, Westend, Brittany Graveyard, and Etceter. (During the Cataclysm) The lunar rifts, linked to the lunar phases, were disrupted and went dormant. The moons remain devastated, but the lunar rifts are once again functional.

Usage
Lunar Rifts are located in Solace Bridge, Highvale, Blood River, Brookside, Owl's Head, Westend, Brittany Graveyard, Etceter and Isle of Storms. Depending on the current moon phase (shown under the compass at the top of the screen), one of these will be the active destination. When entering any of them during that phase, you will be taken to the active destination.
 * If you're already at the active destination and you enter the Lunar Rift you will be taken to Isle of Storms and can enter there and be taken back to the active destination.

The Lunar Rifts are only active during certain moon phases. The moon phase changes every 8m45s Earth time, for a total of 70 minutes. The list of phases, in the order they occur, along with the active destination (for phases where the Lunar Rifts are active) is below.

The Lunar Rifts have columns immediately surrounding the center. These columns have pictures on them which correspond with the moon phases in which the Rifts are active. You can lookup earth moon phases to see which picture corresponds with which phase if you're curious.

''Tip: the seconds and last digit of minutes will always be the same for each phase. For instance, the Earth time for Full Moon always ends in x5:00. (As long as you are in a full-hour offset time zone.)''

Trivia

 * Very early discussions about how the worked can be read here Lunar Rift travel on the Official Forums.
 * Lunar Rift are possibly a reference/recreation of the Moongates from the Ultima Series. Both are a series of gateways that function via the moons' power. Late in the Ultima series, the Moongates stopped functioning.
