Toruchain

"Not to be confused with The Torus Chain."A Toruchain is a verse that is composed of two interlocked torus-shaped objects, one always is a primary color (usually called the primary hemitorus), the other is always a secondary color (usually called the secondary hemitorus). A Toruchain is the combination of both, with the name coming from both hemitori being 'chained together'. A toruchain is opaque because it is almost filled with Torukuverses.

Color
The color of the hemitori are created from a spectrum, from what Torus Chain verses are most common within it. Hemitori are unstable if the most common Torus Chain verses are gray, causing some Torukuverses to be able to float inside them. Alternating colors of hemitori attract, creating a Toruchain.

Categories
Because of how Toruchains have to be primary-secondary, there are 9 categories of Toruchains, one for each kind of primary color (red-yellow-blue), and one for each secondary color (orange-green-purple).
