The Crysilac was once a crystalized creature. They ventured too far out of the borders of the crystal grove and found the truth of the grove. As they went further and further, they became weaker and weaker; their soul linked to the grove. Few crystallized creatures who ventured over the borders, away from the demiplane died before being able to return. The bodies of the creatures that managed to return, suffered from aggressive reassimilation. Their bodies fully turning to crystal, now roaming the borders of the grove, keeping any that want to leave inside.
Ignorance Punished
Many creatures can turn into a crysilac, although mostly unintelligent creatures are unaware of their dependence on the crystal grove and thus ignore its boundaries. Some immediately recognise danger once they pass its border, while others ignore their tiredness and venture on. Only those who return on the brink of their life befall the ill fate of becoming a crysilac.
Different Sizes
The size of a crysilac depends not only on the size of its former life, but rather its lifetime. In their time back into the crystal grove, the intake of the Hyxia crystal’s power has not gone back to their original state; their bodies still in shock and clinging to any energy they can find. In due time, it causes the crysilac to grow larger, gaining more of the grove’s power under their command.
