From publisher blurb:
A 5th Edition Mini-Dungeon adventure for four level 7 PCs
Kazzak the Impure, a recently matured dark naga, has recently been banished from the intrigues and horrors of his mother’s nest. Like the rest of his foul reptilian race, Kazzak is paranoid, covetous and domineering. However, unlike the rest of his nest, a vile contamination within Kazzak’s bloodline has recently surfaced; Kazzak is struggling with the earliest stages of his burgeoning sorcerous powers and is naturally drawn to the dark powers of necromancy. However, his skills are weak and untried; the dark naga has not yet developed sufficiently to gain any levels in sorcerer.
However, fortune has favoured Kazzak. Having easily dominated or bound a small number of followers to his side, his group have helped him locate and enter an ancient library deep beneath a set of scorched ruins. He has successfully defended his new home against a number of treasure hunters and interlopers, whilst steadily reading the many tomes and librams that surround him.
