Some field notes on Trolls, courtesy of T.H.I.S.
Ghorion was once one of the Three Troll Kings of the Cloudsteeth Mountains. Undeath has only made him crueler, and much, much more powerful.
They were formidable even before they learned how to use weapons.
Nahactl, the Wanderer
The Trollshaw Staff is roughly six feet tall, though if the bends in the wood were pulled out straight, the staff would easily be eight or nine feet tall. As it is, it is twisted as a troll itself.
The Yugzhee, or "hedgehog-people", guard a great, secret treasure inside their giant burrowed lair. The mysterious Wall of Keys, a 12'x10', foot-thick, cold-iron, "wall", upon which, on iron hooks, hang 100 ornate iron keys of all shapes and sizes. Each key opens some heretofore un-openable barrier, door, or gate, in the particular game world of choice.
The PCs have come upon a great boon, except for the fact that the keys cease to function properly if separated from the iron wall for more than a few minutes. Higher level characters will be able to figure out how to take the wall "with them" via magic. Lower level characters will have to get creative.
