Chrysalis City Edge of Dawn Town, where the road meets the forest
Officially an archive of old research papers, decommissioned equipment, and sample collections, the Outer Storage Facility occupies a squat, windowless building originally constructed as a power station for the old mine network. Its current purpose is more interesting than its name suggests.
Access requires a letter of recommendation from a faction representative of sufficient standing. The building’s interior is larger than expected. Navigating to its significant rooms requires either authorisation or the correct sequence of elemental keys derived from the geometric shapes of the old civilisation.
Two rooms are of particular interest. The portal room contains a transportation circle connected to the Highland Plateau—the same plateau where the geometric portal of the old civilisation stands. The hidden library, behind a concealed wall, holds an enormous collection whose text shifts and shuffles to conceal contents from unrecognised visitors. Those the library knows need only think of what they are looking for.
Access: Letter of recommendation from a recognised faction representative, or the correct elemental sequences
DM note: Portal room sequence: IIII - IIUU. Hidden library sequence: IIII - IIIIIIII - UU - IIU. These correspond to the Platonic solid shapes of the old civilisation.
