Titansgrave

Throughout the world are signs of an ancient race. Bones, armor, even ruins of colossal architecture.

The Giants claim that they are the ancestors of their people (1). This is taken as evidence of the giants' divine right to rule (1).

And at one time the giants did rule. It was a time of great wars. So much energy from those battles are inherent in the scars it left on the land. This includes the endless battles of the Frozen South, where the wind whips up shapes of forgotten heroes three stories tall. It is for this reason that the giants will never recognize the authority of Grigori.

Titansgrave is more of an idea then a singular place. Unless that was the name of the planet to the giants. A way of honoring their ancestors.

The Titan's Goblet stands on conventional terrain, but its inhabitants live along its rim in a world all their own. Vegetation covers the entire brim, broken only by two tiny buildings, a Greek temple and an Italian palace. The vast waters are dotted with sailing vessels. Where the water spills upon the ground below, grass and a more rudimentary civilization spring up.

Frost giants are so interested in death rituals because they are trying to bring back the titans
The dragon under the volcano once belonged to the fire giant there and served as his mount.
The time of dragons was overtaken by the time of the giants. The titans claimed this planet in the last battle and The empyryeum that lived there were eventually overtaken which were eventually over taken and the giants don't want the world to know they have failed..

The lesser races in the form of the undying don't want the other things back without having first solidified their defenses which are the players.
