Geometric Magic: Well, not magic, no. But a lot of the Flamic rites and rituals make use of sacred geometry, as reflecting the perfect order of the conceptual universe. Elmiríën, in particular, as eikone of order, structure, stability, perfection, and proper functioning is very fond of these, to the point of self-representing as a perfect orrery of Platonic solids.
Also, there’s a lot of geometric engineering.
Well, magic is usually part of a religion anyways.
and any sufficiently advanced technology seems like magic. 😛
