Ardanium II, a substance sharing characteristics with the mineral Ardanium, exhibited an increased potency when exposed to radiation. However, this amplification was significantly less pronounced compared to Ardanium, rendering it a more secure option for lower-power energy applications. The inhabitants of Aurilia on Dathomir employed refined Ardanium II energy in their defensive turrets.
In Star Wars Galaxies, Ardanium II energy served as a resource exclusively acquired by defeating Sith Shadows. Artisans required this energy to construct various items essential for the continuous protection of Aurilia. This resource, alongside the entire village of Aurilia, was eliminated from the game in November of 2005.
