It is possible that these stars were made in the studio, and not in places of deprivation of liberty. Above the star appears to be the inscription Sigil. A sigil is an occult symbol, or a combination of symbols that have magical powers. With its help, magicians, alchemists and others summoned and controlled demons or spirits. It was popular in the Middle Ages and played an important role in spell books. In addition to spells, sigils could be used as an emblem of some kind of community, since the word sigil itself is similar to the Latin sigillum and is translated as "seal". The sigil may also be related to the Hebrew word segulah, which means "action or element of spiritual influence."
A Sigil tattoo can mean anything, including belonging to a community, or it can mean nothing.
