[@ClocktowerEchos], here's my take on the Glade of Lost Knights. Sending thousand knights to find one man would be wasteful, and the nation's army would be thousand knights short in the next war. Instead, how about a few knights, a dozen or less, setting out to find the royal offspring across the four corners of the world. In the end, they would end up to the Glade, and died there, the place's powerful magic reanimating their armours and weapons.
