The Hall of Wisdom on K'tau is an underground chamber and a place of worship and communication with the gods. Through Asgard technology, a beam from the obelisk in the temple transports visitors to the underground chamber where a recorded holographic projection of Freyr speaks words of counsel. SG-1 also contacted Freyr and the Asgard High Council through live holographic communication from the Hall of Wisdom.
