Ladrion

A ladrion is a material that is used as a weapon.

In 2376, an unknown vessel attacked the USS Sungari, with Nog and Thirishar ch'Thane aboard, with a directed ladrion pulse. The ladrion pulses severely weakened the runabout's shields. 

Also in 2376, the USS da Vinci was attacked by ladrion bursts from Biron's Androssi ship.
