“He was obsessed with the colors of the overworld,” the resident said. “I was his senior assistant, with two others under me. We were just village lads, though quick to learn. He established himself here because, he said, the conditions were unusually propitious — a unique quatrefoliate intersection of planes, a node from which it was possible to reach deep into two adjacent dimensions of the upper world, and one of the infernal.”
A tooth-rimmed sucker, sensing the flavor of his breath, probed for his mouth, but Grolion knocked it aside. The resident spoke on. “He particularly craved to see a color known in the overworld as refulgent ombre. It cannot exist in our milieu; what we call light is but a poor imitation of what reigns there.
“But our village sits on the site of Fallume the Ept’s demesne, long ago in the Seventeenth Aeon. So potent were the forces Fallume employed that he permanently frayed the membranes between the planes. My master’s researches had shown him that, here and here alone, he could create a facsimile of the upper realm and maintain it indefinitely. Within that sphere he could bask in the glow of refulgent ombre and other supernal radiances. To do so would confer upon him benefits he was eager to enjoy.”
The details followed. The microcosm of the overworld sphere would spontaneously self-generate upon completion of a complex design made from unique materials: the pigmented scales of four kinds of butterflies whose larval forms fed only on the sap and leaves of a unique tree, with which the insects lived in symbiosis — predators drawn to consume the insects were led into its maze of branches, where they impaled themselves on barbed thorns and thus became food for the vegetative partner.
The tree had a unique property, being able to exist in more than one plane at the same time, though it presented a different form in each milieu: in the first level of the overworld, it was a kind of animal, a multilimbed hunter of the transmigrated souls of small creatures that evanesced up from our plane; in the underworld, it was a spined serpent whose feeding habits were obscure, though distasteful. The attributes of all three realms coexisted in the tree’s inner juices. Eaten and digested by the worms that crawled the branches, the ichor was transmuted by the process that turned the larvae into butterflies, and was precipitated out in the scales of their viridescent wings. Taken while fresh, the colors of the scales could be arranged, at this precise location, into the design that would cause the facsimile of the overworld to appear. Within that sphere, refulgent ombre would shine.
Grolion halted the resident at this point. I saw his energetic face in motion as he sorted through the information. Then he asked the question I had hoped he would: “This refulgent ombre, is it valuable?”
“Priceless,” said the resident, and I saw avarice’s flame akindle in the assistant’s eyes, only to be doused as his prisoner continued, “and utterly worthless.”
Grolion’s heavy brows contracted. “How so?”
“It can only exist in the facsimile, and the facsimile can only exist here, where the planes converge.”
Grolion turned to regard the workroom. “So the starburst cannot be moved? Or taken apart and reformed elsewhere?”
“Disturb a grain of its substance, and it will depart through the breach, taking you and me, the house, and probably the village, with it.”
A scowl pulled down the vulpine face. “Tell the rest.”
“The master erected this manse, laid the garden, planted the tree. The village council welcomed him; in recent years traffic along the road has become scant; wealth no longer flows our way. They made an accommodation: the village would provide him with assistants and sundry necessities; he, in return, would perform small magics and provide the benefit of steagle.”
“And what is this steagle?”
“It is an immense beast that swims through endless ocean in an adjacent plane — you will understand that the terms “ocean” and “swim” are only approximations. He gave the village the knife that cuts only steagle; slice the air with it, and a slab of meat appears. With each cut, a new piece arrives, dripping with lifejuices. We would never know hunger again.”
“A useful instrument.”
“Alas,” said the resident, “it, too, only works where interplanar membranes are weak. A mile beyond the village, it is just another knife.”
Grolion scratched his coarse thatch. “Does the steagle not resent the theft of its flesh?”
“We have never given the matter any thought.”
