Thunder Spike
A jagged, lightning-like spire of burnt wood built to commemorate Hoval the Unflinching, a local hero of legend who transformed into a thunderstorm to drive off a cloud giant. Travellers pay respects by driving iron spikes into the spire. This requires a bit of climbing since the lower levels are completely covered in spikes. Anyone who drives a spike into the pole gets a +2 to their next saving throw against lightning.
A small marketplace has grown up around the spike as caravanners camp to make use of the nearby stream. A few locals sell iron spikes, useless protection charms and small blackened casks of wildberry wine. Bearded mystic Volian Ulot wanders the market, an enormous possum on one shoulder. He claims he knows the secret to Hoval's transformation, a secret meditation technique on a secret ledge high up a cliffside, which he will share with the credulous for 300 silver. Locals revere Volian, though none of them can afford his price. The final step of Volian's meditation is getting pushed off the cliff to your death.
