The Lost Memories of Agolla - Maraone, The Reptilian?

It seems that at the entrance of Agolla there was a huge serpent-like creature dwelling in a cave. It was called Maraone, and was so aggressive to attack every one coming out from or going into the village.
We found other toponyms in the area suggesting that Maraone was something more than a legend, and that its presence was felt heavily by the Agollans. As for Maraone's whereabouts, it appears that at some point in time it simply vanished, leaving behind only the cave and its mystery.
