High Priest Gregory:
Asefa is the chief shaman and guide of dead souls of the Ketra Orcs. Udan Mardui holds the same position among the Varka Silenos. Each of them possesses a Divine Stone of Wisdom which is a fragment of this Stone of Commune. Bring one of the stones to me.
Both tribes seem vaguely aware that the stone contains powerful magic and mysterious knowledge, but they have no idea how to access it! They actually give it away as a prize to the person they think is smartest among them!
Prove your wisdom to Asefa of the Ketra Orcs or Udan Mardui of the Varka Silenos and they will give you the stone.
Which tribe would you prefer to obtain the stone from?
"I'll deal with the Ketra Orcs."
"I'll deal with the Varka Silenos."
