I would think that there is a subtle enchantment placed on the stone, that discourages the simple folk from interfering with it. Or maybe they just register on some level, hidden to them, that damaging the stone would be a very bad idea.
Of course, once someone else finds out, and rushes in to break it up into nice little pieces... ouch.
The scholarly details could recieve more power, if the players find themselves on the opposing side of would-be-miners. What if there is a prophecy, that something unnatural and terrible will happen at the Stone? Unclear as prophecies go, it could be that somebody plans to create a massive stone golem (or few) for some real muscle - and that could be also a real plot.
But there is also the Stone itself - so off with the PCs to hunt for more knowledge about it, and inevitably about the forgotten people of the region. With a few unclean legends of the scourge of their time, or some pictographic burial findings, they should be able to piece the big secret together.
Suitable for groups that like research of this kind, though.
Nicely executed and has a lot of scholarly details (I am not sure where anyone dealing with this would get those, but we move on). The piece is generic enough that it has dozens of uses in dozens of ways.
This one could be a modern or supers submissions as well as just a fantasy one.
The Dragon can easily be swapped out for any similar Mystic Scale monster, all one needs to do is change the meaning of the word Haern. If desired, I can add the dragon as a sub, but there are enough suitable dragons out there to fit the bill. Go to Comment
Will be converting some of the notables in this sub to Stubs and then Subs as time allows.
In some ways it's like making an onion - you always need to add another layer :)
I will be elaborating on the home city, its politics and culture as time allows, but for now it is a large, middle-easternlike maritime city. There are two major ethinic division with the minority in power. Herithi is part of the majority which is oppressed, Cardos (and all other government figures) are part of the minority.
