From the Koshi, the characters may learn about Ar´Ruga, also known as „Mad-Two-Head“. A long time ago, Ar´ Ruga was a Koshi like any other (perhaps a bit more courageous), until he found three blue glimmer stones in an old ruin. He loved them, loved how they glittered and gleamed and fashioned them into a necklace of leather strings and semi-hardened resin. He was so found and proud of his necklace that he then began to venture out into the jungle for days at a time to find more of them. Over time, he changed. He became dumb and careless, and even forgot to hide from the rain when it came, so he began to mutate. That was a year ago.
