Miriano the byrdle told me about the Abyss. The Abyss is located at the Fray Fields. By his words it all started with some "crystal" (more research needed of the kind of it) that was consuming the energy around it including the earth one making the hole deeper and deeper making the "abyss" to appear.
He showed me the nullstones. They store the energy called "Residue". Can be potentially used to store magic energy if I find way to convert the residue back into mana. Needs a further research.
