Info about Ink Creatures:
Ink creatures were usually once beautiful and colourful creatures, or magnificent art pieces, or anything that one can find pleasure in. But sometimes something happens to these poor creatures, turning their insides to an inky substance and their bodys often becoming glass. If cracked they leak this fluid from the crack.
Often the creatures are outcast and once remember how they were revered amongst society, so they are often seen crying. if you can call it that.
