Tridymite (Mind Player)

Tridymite is an Original Character owned by The Mind Player. It first appeared in the Role-Play "Kindergarten".

Personality
Tridymite is a shy and naive gem, as it was made on an unknown planet and solar system fairly recently and was isolated from any gem interaction for many years. After being created, it was taken in to a small facility in the planet to rain and be taught about gem society, but upon seeing a gem kill various other in a live report, it ran away to the wild on the non-colonized areas of the planet, isolating from gems for a long time. This isolation and previous trauma, led to the gem to be extremely furious and paranoid upon seeing one.

It has a deep emotional connection to the creatures found on his native planet, so much so, it has tried to sacrifice itself for them, risking its life in various occasions. This connection goes so far, that the creatures will obey its orders most, if not all, of the time. Its hatred to gem makes him more susceptible to non-gem beings' influence, feeling attracted more to them, than to gems.

Abilities
Alike most gems, he is capable of shape-shifting, reforming,

Mineralogy

 * Tridymite is a high-temperature polymorph of silica and usually occurs as minute tabular white or colorless pseudo-hexagonal crystals, or scales, in cavities in felsic volcanic rocks.
 * Its chemical formula is SiO2.
 * The high temperature form occurs most notably as vapour-deposited, platey crystals in vesicles in some volcanic rocks, also rarely as phenocrysts in some felsic volcanics, or as a contact metamorphic material in some hornfels.
 * Tridymite was first described in 1868 and the type location is in Hidalgo, Mexico.
 * The name is from the Greek tridymos for triplet as tridymite commonly occurs as twinned crystal trillings (compound crystals comprising three twinned crystal components).
 * Tridymite can occur in seven polytypes and the most common at standard atmospheric pressure are known as α and β; both commensurately and incommensurately modulated structure variants are known.
 * Below 100°C the triclinic form, α-tridymite is stable; there are also orthorhombic, monoclinic and hexagonal polytypes stable at higher temperatures.
 * The orthorhombic β-tridymite polytype is most stable at elevated temperatures (>870°C) and it converts to β-cristobalite above 1470°C.
 * However, tridymite does not usually form directly from pure β-quartz, and it is usually stabilised by alkali metals. Otherwise β-quartz transitions directly to cristobalite at 1050°C without occurrence of the tridymite phase.
 * Some polytypes of tridymite ( from Deer et al. 2004):
 * In the above table, M, O, H, C, P, L and S stand for monoclinic, orthorhombic, hexagonal, centered, primitive, low (temperature) and superlattice. T indicates the temperature, at which the corresponding phase is relatively stable, though the interconversions between phases are complex and sample dependent, and all these forms can coexist at ambient conditions. Mineralogy handbooks often arbitrarily assign tridymite to the triclinic crystal system, yet use hexagonal Miller indices because of the hexagonal crystal shape.
 * A low temperature form is commonly reported as a constituent of certain types of opal, intergrown with cristobalite (opal-CT), found in many environments including marine sedimentary rocks derived from biogenic opaline sediments, and low temperature cavity infillings, replacements, etc., including some precious opal (Sanders, 1975).
 * Some wood opal is mostly tridymite (Mitchell & Tufts, 1973).
 * However some workers note that opal is hydrous and lacks any long-range ordering, the opal structure just mimicking cristobalite and tridymite, so may not contain true tridymite (Smith, 1998).
 * Large tridymite deposits have been detected on Mars, but the nature and origin are uncertain (Lakdawalla, 2015).
