Ok working on the Karameikan/Darokin Border with Canon(sometimes faint like the Mystara Novels) and Fanon(which helped a lot) I found and created this region.
The Giant's Vale
by RobinThere is a valley between Karameikos and Darokin (in the NW) where Stone Giants have lived, close to the Solomonari.
As being generally a pacifistic race (see my material on the Broken Islands Archipelago) the Stone Giants were enslaved by the Nithians and the Taymoran
This period is reflected in the naming of the Giant's settlements in this region.
Eventually these giants rebelled, merged with several Hill giants for battle prowess, and the Nithians or Taymorans reacted.
The Giants had build a 5 mile vastle wall Castle blocking acces to their valley, yet lacked strategic awareness.
The opponents slid along the lake in the west and attacked the giants from within. The settlements destroyed and The Great Wall partially destroyed, able giants surviving were 'dragged' away into servitude.
Some remaining Stone giants giants hid in the hatching caves, and continue to do so now.
The nearby Solomonar giants were affected by powerful magic attacks from the otherside, and this magical battle and its magical residue was the reason crystals would eventually spawn in this region centuries later (897AC), when more magical residue was added. These deadly crystal effects largely seperated the Solomonar valley from Darokin since that day, and horribly killed many humans and animals and plants alike in the region up to today.
Since this happened, the Solomonar use only the passage into Karameikos, through the Giant's Vale, where new Hill Giants resettled in the last decades, living in peace with the Stone Giants. These Hill Giants have taken control of the ruined Great Wall Castle. Only recently some adventurers succeeded to use a small section between the crystal affected area and the mountains to rediscover the Solomonar Valley.
Here is the map of the region so described
