The demo follows young King Solomon. The planned full game follows the Seal-bearer in Jerusalem, in the fourth year of Solomon's reign. Every night, something tears down what the masons raised that day. The archangel Michael brings the king a Ring, and the king puts it on your hand.
In the planned full game, you are the Seal-bearer. Weaken a wild spirit of the Ars Goetia, the grimoire attributed to King Solomon, and the Ring's seal descends, draws it up in light and folds it into a brass vessel: creepy-cute familiars at first, and in the full game the terrible Kings. Battle beside them. In the full game they also go to work on the Temple, a house built without the sound of iron.
Then the king commissions a head of brass that answers every question. It is never wrong. That is the problem.
Solomon's Seal sets pixel art in lit 3D dioramas of the ancient world, with a soundtrack synthesized as you play. Scripture is quoted from the King James Bible with chapter and verse. The angels are as Ezekiel saw them, and you cannot bind them.
