Temple of the Four Aspects

Carved directly from the cliffside, this monastery to the four-faced god has stood for millennia. With polished marble floors and a serene reflecting pool, the columned central chamber houses silent monks, each dedicated to an aspect of the god. Down the flanking hallways, massive statues dedicated to this god stand in tall chambers, silently watchful. If a pilgrim can please each statue aspect of the god, the doorway at the end of the chamber will swing open, granting access to items blessed by this deity.

How would you use this map? What god would it be dedicated to and how could the party prove their worth and claim the holy artifacts? Let me know in the comments!
