Magic suffuses all existence in the worlds of D&D. In the Forgotten Realms, scholars describe the fabric of magic as a Weave that allows spellcasters to interact with the world’s underlying magical reality. In Arcavios (the world where our story takes place), that fabric is knotted and tangled in some locations, creating a phenomenon called snarls. At these places, spells can be amplified or distorted in unpredictable ways. This phenomenon matters for Strixhaven because a luminous snarl is situated at the very heart of campus, located in the Hall of Oracles in the university’s monumental library, the Biblioplex.
Similarly, gravity-defying arch shapes appear throughout the world of Arcavios and, in particular, tower over the Biblioplex. These star arches are made from spokes of natural materials that float in an arch shape, with a precise inner curve and a rough and irregular outer arch. They can stand straight or lie at an angle, and they can be small or enormous, whole or broken, grown over or mysteriously clean. Their irregular spokes evoke the radiating lines of a shining star.
The star arches are a mystery left over from the birth of the world. In most cases, the arches simply float inexplicably—silent, immovable, and inert. But many people report seeing an arch appear to them at a critical juncture in their lives, helping them understand a lesson or answer a burning question in their mind. Some scholars believe each arch marks a place of great magic, such as the site of a great mage’s birth or the location of a time-lost spell. Other folk believe these arches are connected with the archaics in some way (see Archaics and the Oracle). Some students have even seen an arch come to life with magic in an archaic’s presence.
Both snarls and star arches are subjects of magical research for students and faculty at Strixhaven, who also study wild and dead magic zones, floating earth motes, and other weird locales.
