Constructs are the oldest type of Alacrian technological. Since the later reanimators and amalgamators originated as wartime concessions to manufacturing efficiency, constructs are still prized as the most advanced of the three categories. Although many of their more violent varieties are a product of the Draconic Wars, constructs originally served many civilian purposes throughout the Alacrian Golden Age. In fact, their origins go back even farther, being essentially a refinement of late First Era industrial robotics. Once advances in computing could afford such robots a greater degree of intelligence and independence, and once adamantology had enhanced their physical abilities, Rationalist philosophers began affording them the title of "constructed lifeforms."

    Unlike many of the later amalgamators and virtually all of the Muse-deprived reanimators, constructs can often be found still fulfilling their original programming after the Fall. Some may continue to repel the Subject Species from Alacrian ruins, but virtually none will leave their ruins to attack modern settlements. Their more predictable behavior, as well as their more advanced capabilities, make constructs a dream find for the typical necromancer. However, many necromancers also make constructs the last type they learn to bind, for one disappointing reason: these techs are found much more rarely than the others. Additionally, military models can be rather difficult to neutralize without grievous damage.

    All constructs have natural armor ranges and cannot wear normal armor; their armor may still be described by material, for the sake of interaction with other rules. Unless otherwise stated, they have two hands and wield handheld weapons normally; some constructs have more than two literal arms or hands, but are still considered to have two hands for rule purposes. All constructs have shadow vision, seeing in any Low Light environment as if it was Medium Light. Because of their great reliance on computerization and metallic structure, constructs take 150% electric damage.

    Because constructs do not incorporate expendable materials into their structure as other tech types do, they are the least efficient type in regards to their use of repair materials. A successful repair roll expends a pound amount of repair materials equal to the damage repaired.

    Military constructs are typically powered by insendite crystals like reanimators and amalgamators, while most civilian models are recharged by stationary charging stations in Alacrian ruins. In either case, for bound techs, their initial power level is typically sufficient to last for an entire adventuring campaign.

    Very different from other constructs, the military combæn was an adaptation of adamant swarm technology used for confined-space cleaning and maintenance in industrial facilities. Each "one" is decentralized into hundreds of interchangeable blades, plus several redundant processors, eyes, and insendite housings. They are notorious for being deceptively difficult to take down. Still, heavy armor can render them mere nuisances, meaning that they were most often employed against smaller dracomorphs and poorer-equipped Hellborn.

    Rationalism demanded abandonment of sentimentality, especially in the face of terrible hardships such as war. The antecessoroid aesthetic was one such loss. Hailing from the middle stages of the Draconic Wars, sintars were bizarre, spindly, three-armed quadrupeds that rapidly began to eclipse prælitars wiith their amazing agility and speed. Entirely abandoning ranged combat to their rotamortis counterparts, sintars focused entirely on melee weaponry. Often deploying a shield in addition to a two-handed weapon, sintar are infamous among modern adventurers; despite lacking the punch of many other techs, sintars can be nigh-untouchable nuisances unless a party can match or work around their close combat dominance.

    Umbras are an advanced variant of sintar designed for infiltration, assassination, and search-and-destroy roles in the Third Alacrian Era. Although a portion of their mission was eventually usurped by revenants, they remained important in special-forces operations until the Fall, and continue to be incredibly dangerous for adventuring parties who infringe upon their old bases. Umbras which are not seen by such intruders often stalk them for some time, waiting for a particularly vulnerable moment at which to pounce. They are more frequently encountered in Diran territory.

    The imposing numin were deployed alongside asuras, and occasionally even sintars, in order to handle more proficient adversaries capable of both flight and ranged defense. Their arcjet-lined crystalline wings made them favorite spectacles for those who wrote of the Draconic Wars, and they quickly became a symbol of hope and courage throughout Alacrian militaries. Later, in the Third Era conflicts, their reputation became more one of fear - a legacy that lasts to this day, whenever adventurers draw their ire within or outside old military ruins.

    Asuras were produced as bodyguards for the wealthy and ruling classes of the late Third Era. Appearing initially as finely-polished antecessoroid knights, they quickly reveal their true capabilities if engaged, splitting their two arms into four and grotesquely unhinging their bodies and legs for maximum mobility. Both today and long ago, they are widely esteemed as the ultimate close combat technological, and the pride of any necromancer skilled and lucky enough to bind them away from their decaying defense protocols.

    The massive agnicaras represented a significant departure from the Alacrian preference for small, finely-engineered constructs. Often viewed as a middle ground between techs and vehicles, they carried vehicle-grade weapons and techshields, though with simplified combat-technique programming due to the processing requirements of their power generators. Originating long after reanimators and amalgamators dominated Third Era armies, the presence of agnicaras is a sure signal of a military location the Ancient Ones deemed vital to protect.
