Axiom Carapace

This magnificent suit of full plate is forged from dark star-iron and lined with silver-threaded midnight silk. Violet light pulses beneath its surface like a second heartbeat, while angular runes shift position whenever the wearer casts a spell. A faceted crystal set into the breastplate contains a slow-turning miniature constellation. The armor is surprisingly light, and its sealed helm opens into a crown of hovering plates when its arcane defenses awaken.
