The peddler was pulling odd things from his pack, extolling each as he laid them down – one shoe that changed colors, a knife carved from wood, a mummified bird. “And this,” he said, pulling a 1 foot square box of stone out of his pack, “is all the friends you will ever need.” He opened it up, showing the carved stone statues of warriors inside.

For a mere thousand gold! A bargain!”
The High King is dead. He died on a quest to find the stolen Crown of Destiny. As he died, he activated the ability on his armor, Fly To The Four Winds, which randomly transported his sword, Cut-Steel, and his shield, The Shield of Hope, to far-off places so they would not be taken by his foes.

The outer wall was so gently sloped that it would have only stopped a horde of hobbling old men, an able-bodied soldier could stride up to its crest with little effort. Within one saw a huge, nearly perfect bowl-shaped area with the base of the tower in the centre, covered in hundreds of mirrors.
This structure is a massive solar collector designed by the Wizard-King Aardwal in centuries past. He used the concentrated light in his investigations into the magic of light, and in the fashioning of flash crystals.
