You have found yourself soulbound to the Nexus Arcanum, a magical focus of the highest degree. In its true form you will find that the Nexus Arcanum takes the shape of a perfectly fitting indestructible palm-sized orb that alternatively takes the shape of a ring of your own design. Alongside the Nexus Arcanum you will find a source of magic within yourself that grows with use and is directed by your intent. At any instant you are able to recall your focus to your hand, additionally your focus can be stored inside and summoned from your magic source with a moment of concentration.
As a novice wizard beginning to embark on your journey, the Nexus Arcanum starts off as a basic magical focus with no enchantments. However, as you grow in knowledge and power, you will have the opportunity to layer and weave new enchantments onto the surface of its true form, the orb. Each enchantment should be carefully chosen to serve a specific magical purpose or theme, such as enhancing elemental spells, amplifying telekinetic abilities, or delving into the realm of rituals. Spells can be cast through the focus without any enchantments, although they will be lacking in magnitude compared to spells enhanced by numerous enchantments.
With each enchantment added, the Nexus Arcanum gains more depth and potential, becoming a repository of magical knowledge and abilities. However, the true marvel lies in the Nexus Arcanum’s capacity to reach a critical point in its development, where it can perform a remarkable feat: condensing all the enchantments on the object's surface into a single, minuscule grain.
As the enchantments merge and condense, the magical energy within the Nexus Arcanum intensifies exponentially, amplifying the potency of the enchantments manifold. The single grain becomes the base of the object, serving as the core of the Nexus Arcanum's ever-evolving magic.
You can then begin the process anew, enchanting the surface with a different theme, layering more magic, and, once again, achieving the critical point where the enchantments converge into a new, condensed grain of power. This cycle of enchanting, condensing, and amplifying can continue ad infinitum, allowing the Nexus Arcanum to grow in potency and diversity with each iteration.
