Here is the first of a series of articles/charts to augment a hex crawl game. This chart gives you some interesting ideas for an unusual building found in a hex. To use it, roll a d6 for each column, adjust the results as you are inspired!

d6 Age/Condition Original Purpose Main Inhabitant(s) Other Inhabitants Secret 1 New, well-kept Astronomy Telescope Original creator/staff, unnaturally aged (if building is old) Two children (apprentices or scroungers, as appropriate) The structure is capable of sending a signal (across space? time? the planes?) 2 Old, but well-kept Inter-dimensional Viewer Creators’ descendants, much is forgotten Otherworldly pets, tame Forces in another place/realm are attempting to cross via this device 3 Old with some signs of age Weather Control Wizard Undead (corrupted versions of the original crew/staff? wizard’s recruits?) Some computer panels will work if powered (electricity or magic spells with electricity effects) 4 Old and in very poor condition Oracle to the gods Spirits of the original crew/staff Inter-dimensional beings, scouting for an invasion Hidden compartment with undisturbed high-tech devices 5 Ancient, but well-kept Spacecraft with communicator deployed Stranded crew from another planet or dimension Xenomorph-like creature, easily accidentally revived/released Was built on top of another structure that had another purpose 6 Ancient but partially in ruins Ship that traveled through time Bandits/humanoids (barbarians, kobolds, goblins, etc.) Vermin Has an unplanned side effect: Roll again on original purpose column.
