The Hydradome is built

Construction beginning/end

The hydras, after the horror of Shadetrail's reign, move into an underwater dome.

The hydras used to live near or on the shore of their marsh, creating divine buildings with enchantion magic and collaborating briefly with the anthracites. After Shadetrail, many species accused them of collaboration so they enchanted an enormous underwater dome to be built out of strong, leak-proof glass. The hydras moved in and made the place very convinient for living in. The dragon with enchantion of course got corrupted.
