Incursion of the Chain Devils

From publisher blurb: Three nights ago, strange lights and screams were heard from the local temple of Ishtar. Grotesque humanoids, wearing tattered clothes and wrapped with chains, emerged from the very walls, causing murder and mayhem within. Can the PCs save the temple of Ishtar from the incursion of the chain devils? H3 Incursion of the Chain Devils is a module for 4-8 characters levels 5th to 7th using the first edition advanced rules of the world's first and still most popular fantasy role playing game. It can be used with any older edition of the rules set or modern retro clone, though other editions likely need higher level characters. In any event, magic weapons are a must. Thieves and even clerics are not. As with previous entries in the HS line, the focus is firmly on combat. There are 20 rooms and likely 8-10 encounters. Most of the monsters are backward converted from third edition and full write ups are provided. (Note: the subject matter of this module is slightly suggestive)
