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 adept more than makes up for its size with biotic abilities that are nothing short of godly.
