So in other words, Pan's dining hall is lined with the unearthly dying curses of a planeswalking race. Only in Dwarf Fortress...
That pretty much sums it up. Not an intended feature in this case, but that's not to say that similar themes and elements aren't coming down the road.
I am a grappling with how far I want the ritual tech tree to go before the next version. I would rather not have to later back-adjust existing reactions to add in new consequences, so I've drawn up a rough schematic of what I want to do for tier one and part of tier two. What I am debating right now is whether or not to make separate altars for different spheres, or merge them all into one generic "altar" and let the reactions govern which sphere is being tampered with. The former opens up some opportunity for future additions to the first tier, but the second significantly cuts down on the number of buildings. Seeing as DF does not support subcategories for the workshop menu, I'm concerned that adding a bunch of altars will result in a lengthy workshop selection, especially as more workshops work their way into things. Thoughts and suggestions regarding this are welcome, as always.
The previously unused products of documentation are going to have uses introduced. The "expanded theory on celestial mechanics" will be used in the construction of the
orrery, which is a bulky workshop that will train the teacher and observer skills. The "carved treatise on the effects of gasoline on fire," originally intended to be little more than a Homestarrunner joke, will be used for a tie-in to the second tier of the ritual tech tree.
The first tier of the ritual tree will be entirely functional in this version. The second tier will have a number of buildings available for construction, but these buildings will only be partially functional. Right now, they only contain reactions to get rid of excess building materials for some modest rewards (there is one exception, but I am not finished with it yet). These buildings will have more interesting functions introduced with the next release of DF in the form of numerous new reactions.
It's been a productive day, methinks.
