From the publisher's website:
This week’s Toys for the Sandbox climbs the mountains to visit an elven keep crafted from a giant sugar pine. The keep guards a strategic pass that separates the elf lands from the orc territories. As the Druid/Orc War starts to heat up and the frost giants move further south the keep may find itself on the front lines.
Add to this a reclusive commander, a missing merchant and possibly even a defeated god the possibilities for adventure is almost unlimited. The High Keep offers up 18 plot hooks, 4 npcs a map of the keep and a bit of history. You also get a random rumor table for the region and a random encounter table.
