Nidor, a world given life by titans
A massive lighthouse crafted by former necromancer half elf Peddrox. Serves the eastern border of Yccona, center of the coast. The party discovers that this lighthouse was built unwittingly by Peddrox in service of the hordes of Lamashtu. It’s light serves to calm the chaotic nature of her planar gates, allowing her forces to sweep in to wage war on The eyes of fear and flame.
When faced with the decision to destroy the lighthouse (sentencing the refugees of Yccona to certain death) versus saving the lighthouse from Peddrox (allowing the refugees escape via Yccona’s 5 ships), the party decides to save the lighthouse, defeating Peddrox in battle.
