From the release:
A grand showing of wealth and power, the Guildhall of the Master Builders is lavishly finished in marble. Upon entering the entrance hall, flanked by two huge statues, visitors step over the 'Keystone Arch', the symbol of the Master Builders and synonymous with power in Wardenhale. Through the double doors, visitors enter a vast marble-floored meeting hall, headed by a large arch shaped table. The Elders sit behind the large table, and behind them are meeting rooms and offices where Masons plan and design - and not always just regarding architecture.
