Remalite crystals activating
Remalite was a type of valuable crystalline mineral with acoustic properties.
The Cymari used arrays of remalite crystals to achieve harmonic resonance and power their abilities of cymatic transmutation, with which they used to create structures. Each crystal emitted a unique frequency and the removal of even one from the array would cause their structures to destabilize and collapse.
In 2383, DaiMon Nandi convinced the crew of the USS Protostar to help her perform a "diplomatic exchange" with the Cymari so as to obtain a remalite crystal. When the Cymari failed to offer a crystal of their own accord, Nandi stole one and absconded. Unbeknownst to her, Dal R'El had attached a combadge to the crystal, allowing the Protostar to subsequently track and beam it away to be returned to the Cymari. (PRO: "First Con-tact")
