So who are the Sons of Behemat. It seems there are quite a few AoS players that are interested in them following their lore and background through hints that have been in several books.
Godbeasts?.... OK you have my attention.
Lets take a look at who they are.

In the Age of Myth
As with much in the Mortal Realms, the story of the Sons of Behemat begins in the Age of Myth. Even to the most learned scholars of the Age of Sigmar, much of this time is lost to history, remembered as a time of legends, where the gods walked the realms and great deeds were done. While Chaos had not yet reached the Mortal Realms, they were still places of peril, danger and great foes, and stranger things besides – and there are perhaps none greater (or stranger) than the godbeasts.
Godbeasts
Godbeasts are ancient creatures of vast power that dot the Mortal Realms. Some are worshipped as deities, some are rampaging destroyers, and others are forces of nature untroubled by mortal notions of good or evil.
The godbeasts have been crucial to the shaping of the Mortal Realms. Dracothion, the Stellar Drake, found both Sigmar and the Seraphon in the aetheric void, helping to guide them to the Mortal Realms, while Vulcatrix, Mother of Salamanders, shattered Grimnir in a titanic duel. Some godbeasts joined with Sigmar, while others battled him.
One such godbeast was Ymnog, an enormous creature known as the Grandfather of Gargants. Ymnog was slain in one of Sigmar’s greatest battles of the Age of Myth – but the death of one monster made way for another…
Behemat
Behemat, known also as the World Titan, was one of the greatest godbeasts to stride the Mortal Realms, a being of mountainous size and unruly temper. Behemat, in many ways, was the first gargant, and is their forefather. None quite know for sure how it happened, but at some point in the Age of Myth, Behemat was knocked into a stupor either by prodigious consumption of cattle or Sigmar’s hammer, spewing the entire gargant race into the Mortal Realms before falling into a deep sleep.
The Realmgate Wars
Behemat was awoken during the Realmgate Wars, a major conflict that kicked off the Age of Sigmar following the arrival of the Stormcast Eternals in the Mortal Realms. During this time, Archaon sought to corrupt several godbeasts to tip the balance of power in his favour, entreating the Skaven and Nurgle to corrupt the World Titan. He was almost successful – only the arrival of the Celestant-Prime and the use of the deadly Great Bolts saw Behemat slain – but that was far from the end of the story for his sons.
The Sons of Behemat
These days, gargants are most often seen fighting alongside the forces of Destruction or Chaos, the former fielding drunken, stumbling Aleguzzler Gargants and the latter using mutated, shambling Chaos Gargants. However, there have been times where gargants have gathered into vast tribes, such as those fighting for King Brodd, the self-proclaimed True Son of Behemat.
Indeed, stories tell of even larger gargants, vast creatures closer in size and ferocity to their lost father than their already huge kin…
