Mandalorian Mercenary

While I'vealready conquered this issue with the help of some friends at another forum, I'm still open to suggestions.

The four protaganists, Demos, Thais, Galen and Ebony, are all directly linked to the Composer, who is God. Like in the Holy Trinity in Christianity, the Composer is split up into three distinct parts of a greater whole. The part of the Trinity that links them to the Composer is analogous to God the Son, or Christ. Unlike the real Christ, this part of the Composer is split into four parts, and each character has one of the fragments inside them. What I need help with here is what these shards represent.
