Scroll Heart Tower

Publisher's blurb:

The grand artificer Mibla has been missing for over a hundred days, and more importantly her shop has been closed. Whether to investigate, trade, or loot, our heroes have come to Mibla’s front door. The shop won’t give up its secrets easily though, and the countermeasures the gnomish artificer left in place make things especially tricky. Can they unravel the mystery, or will the constructs within tear them apart?

This is a simple adventure that can easily be dropped into any campaign with minimal preparation. It’s assumed that it takes place in a major city with nobles and magic items to buy, but the meat of the adventure can easily be transferred to any doorway in the world without those trappings.
