133rd Lambdan Lions

Colour Scheme of the 133rd Lamdan Lions

The 133rd Lamdan Lions are an elite and renowned Tempestus Scions regiment of the Ordo Tempestus that are known for working alongside Adeptus Mechanicus forces of the Forge World of Mezoa to help reclaim lost knowledge and arcane technologies.


For over two millennia, the progena that form the many regiments of Lambdan Lions have served as auxiliaries to the Adeptus Mechanicus. Their Schola Progenium facility and Militarum Tempestus training facilities are based on the two moons that orbit the forge world of Mezoa. Ancient pacts mean that the Ordo Tempestus has assigned the Lambdan Lions to fight missions on behalf of the ruling priesthood of Mezoa, in order to reclaim lost knowledge of Imperial advancements or arcane technologies. In exchange, the Scions benefit from all manner of esoteric augmentations, which are fitted to their vehicles or built into their armour and weaponry, as well as a basic understanding of Lingua-technis -- something rare for Scions. Though they have little interaction with the Cult Mechanicus itself -- for Scions care only for their orders -- the 133rd Lambdan Lions' missions continually aid the Adeptus Mechanicus in its search for further knowledge, so they indirectly work to the glory of the Omnissiah.

Unusually for a Militarum Tempestus regiment, the Lambdan Lions will engage in long expeditionary campaigns across worlds that harbour artefacts, rather than preferring missions that involve swift stealth or brutal strikes before retreating. When the situation demands it, the Lambdan Lions will also fight in the shadow of the Collegia Titanica or alongside Skitarii Legions. Mostly, however, they enact the orders of the Mezoan ruling priesthood whenever sanctioned by the Ordo Tempestus. The labyrinthine nature of lmperial bureaucracy means that the Adeptus Mechanicus occasionally issue the Lions with orders even without waiting for official sanction.

Regimental AppearanceEdit

Regimental ColoursEdit

The Tempestus Scions of the 133rd Lamdan Lions primarily wear black-coloured fatigues with crimson-coloured Carapace Armour with gold-coloured trim. Their Slate Monitron and Omnishield Helms are also painted crimson in colour. Their poleyns (knee guards), pauldrons (shoulder guards) are red in colour. When not in battle, these Scions will often wear a white-coloured beret in lieu of their usual omnishield helms.

Regimental BadgeEdit

The regimental symbol that adorns the armour of the 133rd Lamdan Lions is a red chevron worn upon a field of white on their right poleyn (knee guard), an ancient symbol referring to basic Lingua-technis.
