One of the new zones introduced in the War Within, the gorgeous and expansive Hallowfall, has a beautiful yet ominous zone feature.
The zone, like many zones in the War Within, is subterranean and is lit by a vast crystal stalactite which glows like sunlight.
This crystal, Beledar, allows the inhabitants of Hallowfall to live and farm in their hypogeous environment. But recently the crystal shifted from light to void and then back.
And now, every 3 hours (9:00, 12:00, 3:00, and 6:00 Pacific time), the great crystal stops emitting light, and transitions to emit void.
It remains dark for 30 minutes and then once again turns to the light. We know that light and void are part of the same cycle.
