They prefer to use local woods for the pikes, but if they can't find any, they'll go through the trouble of importing some of their cheaper materials. The trees they hang from are all local (if there are no trees, that option goes away). "Fed to the beasts" is disturbingly generic, and I've only written a note down to make beheading check for a head, without actually doing it yet. Same goes for burning alive, buried alive and drowning (they might be immune). I don't think there are any creatures that are immune to being chopped in half though, so they'll always have an outlet once I add that in. Perhaps they could try different things until they get it right, but most of the immunities should be obvious.
I noticed in the log that two elven babies were enslaved and brought to the human town. Then when they were teenagers and the demon attacked, they were both executed, one of them by the demon. It was quite unfortunate. Let me look them up...
Baby #1: Dipane Nutsdreams. Born. Enslaved. Takes up residence in an apartment in Gemtruss. After coming of age, becomes a ranger. Forced to work in the fishery a year later. Flips between fishery and farming a few years. Executed. Never married.
Baby #2: Ricote Beanjade. Born. Enslaved. Takes up residence in an apartment in Gemtruss. After coming of age, marries Pari Weathervoices and moves into that apartment and becomes a farmer. Becomes a mechanic a year later. Three years later, executed.
Let's look at the marriage too:
Pari Weathervoices. Born two years before Ricote. Enslaved at age two in the same attack. Took up residence in an apartment in Gemtruss. Was a fish dissector for six years until being fed to the beasts by the demon.
