The word solstice is derived from the Latin sol (sun) and sistere (to stand still) because at the solstices, the Sun's declination stands still.

Solstitium is about personal thoughts, memories (both lost and found), ideas (not always my own) and emotions.
What its not: poetry, a way to gain attention, any kind of business
