"Hello. My name is KALES. By the time you receive this message, I won't be here anymore. If you wre with my brother ZETAIS, you will have certainly received the first part of the key. I found the second part a few years ago in another area of RHEM, above on the surface. Maybe it was you that helped me back then and informed my brother. The third part must also be hidden here in the caves. With these three parts it will be possible for you to oen the entryway to a deeper, more hidden part of this cave system. There, in an unknown part of the caves, lies a secret artifact."
