The Third Great Company of Fighting men of the Ultra Templar, between 750 and 1250 men will always be formed into this Company.  Formed primarly from the Death World Bariun.  This was the third group of Ultra Templar that were given the right to form their own chapter from so many Templar surving through the years.

The warrior code of this Order is founded squarely on the principles of justice and fairness. Naturally, as Astrates, the Templars' opinion of justice contrasts markedly with that of the Imperium, but it cannot be argued that the Templar often willingly fight for those who have no others to defend them. Templars of the Everlasting Light defended the plague-struck village of Hafbad when no other would, and members of their Order gave their lives to defeat the mighty Shaggoth Brak of the Death Guard Legion. Despite such deeds, the Order has passed into history for another, less glorious reason: the Templars of the Everlasting Light are cursed.

The secret of how they became thus afflicted is locked within the Order's records. Whatever the cause, they find themselves thrown from their bikes at inopportune moments; swords break as a deathblow is delivered; and seemingly stable earth turns to marsh or quicksand once the treads of their vehicle touch it. Only a member of this Order (Kurt von Tzalza) could be struck in the eye by a ricochet that was fired behind him. Only a Grand Master of the Everlasting Light (Sigismund Drak) could be dumped unceremoniously into a cart-load of manure during a victory parade in Altdorf, the only such cart for many miles around. Only one Chapter Fortess, in the entire history of the Chapter, has vanished into a yawning chasm as the result of a freak earth tremor. There are many more varied accounts of this ill-fortune in the histories of the Imperium. Nevertheless, the Templars of the Everlasting Light never want for recruits. To a certain class of nobility, it is better to belong to a famous Order, however unlucky it may be, than to one whose name is unknown beyond the walls of their Chapter Fortess.

The Templars of the Everlasting Light are formed from the Codex Astartes with over 150 of them wearing the Tactical Dreadnought Armour (or Terminator Armour) to form the First Company of the Templars of the Everlasting Light.
