The death of ilKhan Nicholas Kerensky, followed by the election of Jerome Winson of Clan Wolf as ilKhan, marked the first time that the Clans were not led by a Kerensky. Instead of marking the beginning of an age of indecision and uncertainty, the next century came to be known as "The Golden Century." All facets of Clan society experienced a period of intense development and growth during this time. The worlds of the Pentagon were reconstructed, erasing the final scars of the Civil War. Nicholas Kerensky, like his father before him, was elevated to the level of a demi-god, and both his writings and recorded speeches became objects of reverence.

Exploration continued in the Kerensky Cluster, but exploitation of its worlds lagged for two reasons. One was the sheer lack of people trained to take advantage of any discoveries, and the other was the Grand Council's desire to keep Clan society on a short rein. This did not prevent the Clans from bidding for newly discovered worlds. Although most Clans established only small outposts on new worlds, Clan Wolf seems to have taken fuller advantage of what they owned. They established major industrial complexes on the cluster worlds of Paxon and Tiber, despite rumblings within the Grand Council against such extensive colonization.

The scientist and technician castes reached new heights of excellence during the Golden Century. They perfected artificial womb technology, rebuilt the Clans' industrial base, and made advances in virtually every field of endeavor. Not surprisingly, it was in military technology that they made the greatest, and ultimately the most devastating, advances.

In 2854, scientists from Clan Coyote carried the concept of the Mercury BattleMech to its logical extreme by developing a 'Mech with a completely modular weapons system. The result was an "OmniMech," a machine whose weaponry could be completely reconfigured or replaced by a few technicians to suit the situation in just a few hours. This was the first significant improvement of the BattleMech since its development by the Star League, and it gave the Clans tremendous flexibility, which they have used against us to great advantage. Because of the OmniMechs, Clan Coyote enjoyed a considerable advantage until the other Clans could create their own versions. This took several years.

At about the same time the OmniMechs were being developed, Clan Wolf scientists were working on an armored infantry suit. It protected a soldier, allowed him to keep up with 'Mechs, and enabled him to carry weaponry that could threaten 'Mechs. The Wolf Clan used the first of these powered armor suits in 2868, when two Stars of Clan Wolf infantry defeated a light Star of Clan Nova Cat OmniMechs during a Trial of Possession.

Both the battle armor and those wearing it were called "Elementals" because they could fight in any element: air, water, fire, earth, or even space. It is interesting to note that some passages of The Remembrance mention specific elements when referring to the battle armor, which suggests that early versions of the units functioned in specific environments. The scientist caste began breeding larger and physically stronger warriors who could better cope with the strain of wearing the armor. Other technological and biological advances resulted in the Clans boasting troops of genetically superior Elementals before 25 years had passed.

During the Golden Century, the Clans matured into a society totally unlike anything with which we are familiar. Discussions with various Loremasters indicate that it was during this era that the Clans began to foster a hatred for the peoples of the Inner Sphere. Though The Remembrance couches the Clan's sentiments in quasi-religious tones, their view of us is made clear. We are considered unenlightened savages living in luxury, while a far more civilized people is forced to live on hostile worlds far from Terra. In particular, they developed a strong contempt for the five major Houses, whom they consider responsible for the Star League's fall. Clan warriors see the worlds of the Inner Sphere, especially those of the former Terran Hegemony, as virtual paradises, but their view is distorted by both bitterness and idealization.
