O.L.E.Y.

Instead of the common ley shard arcane power source this construct uses an innovative technique originally developed in the Shadowerealm . The Prismatic Oscillation Lattle Yoke, Or P.O.L.Y. is a rare fey-artificer innovation designed to house a living light-spirit within a construct's core. Formed from interwoven lay-threads and bronzed-etched geometric rings, the yoke generates a stable lattice of harmonic pulses that allows a fractal, polygonal familiar to anchor its shifting light body inside the constructs chest cavity. Within the lattice, the primatic form continuously oscillates through micro-fractals, synching with the constructs leyline essence and granting it extended senses, restorative magic and instinctive guidance. More than a power source, P.O.L.Y. is a symbiotic heart-chamber that binds nature, light and artifice into a single living rhythm that beats for both guardian and companion.

O.L.E.Y in its present form is a hand made prototype, and is unique. Its construction requires not only an understanding of leyline magic, familiarity with the Find Familiar spell and an artificer's unique and instinctive skill in the construction of the steel defender. Few magewrights have the breathe of knowledge to even consider the underlying concepts necessary to construct such a device, let alone the practical knowledge.

Its building required access to both materials of the finest quality, and unique arcane knowledge. The access to the fey-artificer inspired P.O.L.Y and an understanding of its creation is required.

The construction of this artifact by the artificer I'carus is centered on the Emerald Span, that vast upland forest whose boundaries are crisscrossed with leyline fractures and natural conduits of arcane energy. Here among the wilde sages, hermit artificers, beastwalkers and ancient druids this talented artificer received an eclectic education in a multitude of disciplines.

Under the direction of a retired ranger turned Battle Smith I'carus mastered the skills necessary to shape steel, inscribe glyphs of power, find and utilize leyline magic at its source. Then he began to construct a unique guardian, its parts forged from stormstruck wood, etched bronze and sinew-like spellthread.

So clever and original was his construction that he garnered an invitation to Toresta Polyarcana Academy for a position as Instructor, a prestigious position seldom offered to anyone not a graduate of that or some other well respected Arcane College.

While it is likely that this kind of hybrid construct will always be rare and limited to only the most knowledgeable and learned arcane technologist, its very powerful and complex power source indicates that leyline shards are not the only possible source for arcane magic and it is unthinkable that when monographs on the theory behind this device are read at the various centers of arcane learning that other new magics will not be discovered.
