Zoisite

Zoisite, first known as saualpite, after its type locality, is a calcium aluminium hydroxy sorosilicate belonging to the epidote group of minerals. Its chemical formula is Ca₂Al₃(SiO₄)(Si₂O₇)O(OH).

Zoisite occurs as prismatic, orthorhombic (2/m 2/m 2/m) crystals or in massive form, being found in metamorphic and pegmatitic rock. Zoisite may be blue to violet, green, brown, pink, yellow, gray, or colorless. It has a vitreous luster and a conchoidal to uneven fracture. When euhedral, zoisite crystals are striated parallel to the principal axis (c-axis). Also parallel to the principal axis is one direction of perfect cleavage. The mineral is somewhat higher than 6 in hardness, and its specific gravity ranges from 3.10 to 3.38, depending on the variety. It streaks white and is said to be brittle. Clinozoisite is a more common monoclinic polymorph of Ca₂Al₃(SiO₄)(Si₂O₇)O(OH).

Transparent material is fashioned into gemstones while translucent-to-opaque material is usually carved. A metamorphic rock known as anyolite consists of green zoisite with black tschermakite and ruby crystals. These rubies themselves are not of gem quality, but nevertheless their color provides a striking contrast to the green zoisite, and greatly enhances the decorative pieces that are carved from the rock.

Dark Kingdom

The Dark Kingdom (ダーク・キングダム, Dāku Kingudamu) is a group of fictional characters who serve as antagonists in the Sailor Moon manga series by Naoko Takeuchi. They are the primary antagonists of the first story arc in every version of the series. They are first introduced in chapter #1 of the manga, "Usagi – Sailor Moon", originally published in Japan's Nakayoshi on December 28, 1991. In some English adaptations of the anime, the Dark Kingdom's name is change to "Negaverse".

Before the events of the series, the Dark Kingdom comes into being in the 20th century when the servants of those who had served the evil Queen Metaria millennia before (in the battle that destroyed the civilization on the Moon) were reawakened. However, in some of the English adaptations, the word "reborn" is used rather than "reincarnation" — it is implied that Queen Beryl and her cohorts were active the whole time even if they did not accelerate activities until the arrival of Sailor Moon. The group is led by Queen Beryl and the Four Kings of Heaven, who attempt to gather human energy with which to reawaken Metaria.
