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.”
