The Voidcallers are surprisingly egalitarian for a predominantly Lawful Evil force. Its members are recruited from the ranks of mostly magic-users and those skilled in stealth such as adepts, wizards, rogues and specialized experts.<br/><br/>The organization is divided according to purpose: Orro himself personally leads the bulk of the field force, which is mainly composed of spellcasters equipped with magics designed to shape and dominate battlefields, isolating enemy units before devastating them with offensive magics and light cavalry charges that are adept at navigating battlefields full of otherworldly hazards, which is usually followed by dead enemy troops being quickly reanimated to cover for losses. Orro's force is all about attrition and hit and run tactics.<br/><br/>Whispers has command of an elite unit of assassins whose sole purpose is to eliminate key enemy figures and sow chaos along enemy forces. They don't usually take the battlefield en masse, but when they do they usually follow Orro's cavalry and clean up stragglers, and destroy siege engines. They do not leave survivors.<br/><br/>Nashandra controls his light infantry and serves as his strategic advisor, since she is even more experienced in warfare than he is from her time as an Erinyes fighting in the Blood War. Her troops take the field with Orro's and reinforce his own troops' ranks with shield walls backed by longspear-wielding second-rank troops. In a pinch these guys use their summons to temporarily buff up their ranks and absorb the enemy's initial charge, but their main job is defending Orro's warmages.<br/><br/><br/>Overall, Orro never charges first. He lets his enemies come to him through a field of deadly defensive spells and traps, and if they don't they get to suffer a hail of destruction from his warmages. It's a lose-lose situation: stand there and get pummeled, or advance and get worn down then overrun by his favorite tactic:<br/><br/>Orro's favorite tactic is the good old-fashioned Zerg Rush, wherein he has his forces all summon monsters and charge en masse to overrun enemy lines, with the spellcasters advancing behind the summons, cavalry and infantry.<br/><br/>All three arms of his forces are trained to work on tandem, and they know that their specialized skills and training make them too valuable to waste lives, so if they have to they will retreat to minimize casualties, and they prefer to be a constantly-moving target.<br/><br/>If his forces have a weakness, it's that they don't make much use of siege engines, so they have a hard time with heavy fortifications if they can't undermine those defenses beforehand.<br/><br/>Enemies who get close to Orro and his elite guard usually get torn apart by a storm of chained eldritch blasts and Eldritch Glaive attacks from flying warlocks on the retreat.
