Kapitel 1770: The Two Foundations.

Only the core of the altar didn't require them to be godlings to purchase. It cost them 1,000 divine crystals to buy the core.

The core of the altar was a cube. It was black with golden runes on its surface. They took it to the hotel where Legion-3 was waiting for them. It is where they have decided to set it up. 

The altar can be set up anywhere in the divine realm. But it is important that it is set up somewhere safe, as enemies will try to destroy it to cripple the foundation of the god it belongs to. 

The altar will be their foundation in the divine realm, while their Oracles will be their connection to the mortal realm. Together they form a connection that will allow a god seed to receive faith and offerings on their own. Together, they form the weak link of gods. So they need to be protected.
