A black iron door eleven feet tall barred his way. The central panel displayed an iron Tree of Life. Iron lizards clinging to the trunk hissed and, darting iron tongues, scuttled to new vantages; iron birds hopped from branch to branch, first peering down at Shimrod, then avidly inspecting the iron fruit which none dared taste and occasionally producing small chiming sounds.
Shimrod spoke a cantrap, to soothe the sandestin who controlled the door: "Door, open to me, and let me pass unscathed. Heed only my true wishes, without reference to the mischieveous caprices of my dark under-minds."
The door whispered: "Shimrod, the way is clear, though you are over-fastidious in your stipulations."
Shimrod forbore argument and advanced upon the door, which swing aside and allowed him access to a foyer illuminated by a glass dome of green, golden-yellow and carmine-red panes.
