Lunar eclipses are associated with Whiro-te-tipua, the lord of darkness:
Whiro: Whiro is a time of caution, when Whiro-te-tipua is at war with the moon.
Blood moon: A blood moon, also known as a marama kūtia, is a full moon that some say is a warning.
A total lunar eclipse occurs when the Moon passes completely through the Earth's dark shadow, or umbra. During this type of eclipse, the Moon will gradually get darker and then take on a rusty or blood red color.
