We have released a few adventure hooks that could easily be expanded into full adventure modules with a bit of effort. One of the prime candidates is The City of Spiders.
As this hook introduced a whole city for the characters to explore along with factions to interact with it is easy to imaging creating several adventures within this one location.
So there seem to be two types of threat in this adventure. People from the various factions and spiders, large and small.
What I would like to do is gather some ideas of what ‘monsters’ you think complement the classic giant spider? I do not want to end up with a D&D menagerie in every room but I worry that a mono culture could get a bit same old same old fairly quickly.
So my four initial ideas are Drider style half human-half spiders possibly related to the inner circles of the church, Gemsting (giant scorpions) living in the surrounding landscape and giant wasps, the original ecological reason why the giant spiders both evolved and why they are tolerated in the city. Finally, there could be golem or or automata in spider form.
So can any of you come up with really good monsters that could naturally sit in a city dedicated to spiders?
