The volus homeworld, Irune, has a high-pressure atmosphere that supports an ammonia-based biochemistry. To survive on other planets, the volus must wear pressure suits and breathers or, when facing combat, specially sealed armor. Volus are cagey support specialists that use the most technologically advanced power armor credits can buy. Not to be underestimated, the diminutive volus engineer more than makes up for its size with cutting-edge gadgetry.
