GUYS! I FINALLY GOT MY FIRST DRAGON AFTER YEARS OF PLAYING DWARF FORTRESS!!! AND I CAUGHT IT IN A CAGE TRAP!!!!
*ahem*
Sorry about that. So, as I said, I've caught a dragon. I managed to do so before the dragon attacked anyone or anything on the map, and its description lists no kills. I'm hoping this means that the dragon can be safely tamed. I am, however, uncertain as to what to do with it. I do have a cage in my temple which houses a captive Roc, and the two would probably make an excellent pair. However, there are other possibilities, as well, that I don't want to ignore. For example, this mighty dragon might be of great defensive value to my fortress if properly cared for.
One possible use I'm imagining is as... basically a siege weapon of a sort. If I placed the dragon in a 1-tile wide room with fortifications on one side, it could breathe fire at any hostile enemies without exposing itself to much risk. Should the dragon prove unruly, this could still possibly be accomplished by using a drawbridge to block its line of sight until I want the dragonfire. My only concern with this strategy is that the dragonfire might melt the mechanisms controlling the drawbridge, making it virtually impossible to raise or lower the drawbridge once its fire has been unleashed upon my enemies.
It's a shame that I can't get an uncaged dragon to ride in a minecart, as that would allow it to serve as a mobile flame turret.
