Though the Aldar were not as powerful as the Gods, there were many more of them and the Triumvirate knew that they must somehow gather Aldar support if their plan was to succeed. Khalas approached his student, Han-Silnar for support. The taste of resentment towards Proteus for giving Sapience to the humans still bitter in his mouth, Han-Silnar agreed to support his mentor. Han-Silnar assured the three Gods that he could convince the rest of the Aldar to support their side and called a Great Council; something only done twice before in history.

The gathering of the Aldar took seven years and was held in what is now called the Caves of Sorrow. During this time, there was much debate and it became evident that under no circumstances would Dekalb's faction participate in a rebellion and would, in fact, be likely to fight against one. Han-Tolneth's faction wanted nothing to do with either side in a rebellion and just wanted peace, to better continue their research and building. The arguments raged back and forth, waxing philosophic at times and descending to the level of base insult at others. Eventually however, Dekalb's virtue and moral certitude won the respect of all. Han-Silnar was forced to agree with Dekalb and vowed to support Proteus and the other Divinities.
