Alda

Origin - You will shatter just like glass
Alda Ancalagon is one of the main antagonists of Eryr, and is intrinsically connected to the tale of Cassian and Juno both. It is clear however, that for some reason Tael is aware of Alda and Alda is aware of Tael as well, but they have never worked together in any occasion. He seems to be connected to the Depths, but apart from that, he is a mysterious character.
