Era of the Giants

Summary
By using what they call the Ordning, the Giants of this world united into a simple hierarchy that allowed them to become allies. Through this alliance, the Giants overthrew and destroyed many of the Dragon rulers and forced the world into servitude of the Giants for seven thousand years.

37,000 P.C. - 34,000 P.C.
The Giants destroyed the Dragons hold on the world, making sure to hunt down and destroy the most powerful of the Dragons. By isolating the most powerful and killing them, they left the lesser Dragons to flee and fight amongst themselves. Eventually the Dragons all but disappeared or died, leaving the world in the capable hands of the Giants.

Using the Ordning, which detailed the rank of each type of Giant in relation to every other Giant kind, they set up a very workable system of government. All tribes and settlements fell under the sway of a Giant, with bigger populations requiring a bigger Giant to keep it in line. After the initial chaos, the Giants led pretty good lives for a few thousand years.

34,000 P.C. - 32,000 P.C.
The prosperous and gluttonous lives of the Giants began to fall apart around this time. Various infighting between the Giant ranks occurred, caused by some who weren't happy with their position in the Ordning. Various tribes and settlements required more discipline to stay in line, which forced the Giants to wipe out some groups for their constant insolence.

Various new races were created by the Giants in a way to create new loyal followers that would help them maintain control of their lands. These experiments were sometimes less successful than they had hoped.

32,000 P.C. - 30,000 P.C.
It started small, but slowly but surely creatures that were from other planes began to show up on this Prime Material Plane. From the Astral Plane or even beyond, many of these creatures were servants of the Mind Flayers, or the Illithids. As these creatures began to show up, Illithids followed. They took control of many of the servants and tribal leaders, turning them agains the Giants

Eventually, when enough forces had been put in place, and enough of the Giants followers had been secretly turned against them, the Illithids launched a full-scale war...

Signs of the Era
Many races were created during this time. Cyclops, Ettins, Ogres, even Oni started in this era and still remain in the world. The Giants all still exits, but in much smaller numbers and in small tribes mostly hidden in the mountains.

Many mountains ranges today were shaped by the Giants. Some say some of the mountains were created by them, but today historians know for sure that several old, decrepit forts or cities made of stone still linger in many of the mountain ranges today.

More powerful Giants were proficient with magic, which meant that a lot of magical items were made during this era and a few survived until the present. Many of them are related to Giants or their kin, only usable by them or only useful to them. Some are powerful for any user, granting some of the Giant's abilities and some magic items that help carve and manipulate stone.
