Skewers

In the Ocean, Present Time

The armour was as comfortable as skin to wear, moved like fabric, and yet was impenetrable. It was grown, Lyric discovered when she and Niarthen had been fitted, in tanks of ooze, into which, in their human shape, they had been inserted from neck down. It did not take long - forming into a crust over the skin that eventually developed into interlocking scales.

It stretched like rubber, allowing for it to be taken off and on, but once in place protected the wearer both from being sliced by blades and from projectiles – the scales hardening into an impenetrable barrier between Mer and the world. Like much of Mer technology, it was symbiotic, feeding off the wearer, and was activated by signals of stress and adrenaline into the change from malleable fabric to solid surface.

It was also wearable in both human and Mer forms, its surface restructuring around the tail, as Lyric discovered when she and Niarthen had swum to join the army on the journey to the island.
