So I Kinda…

So I kinda spent ages digging out an elaborate (read: planned) underground entrance hall for my latest fortress in Dwarf Fortress. It has halls for crossbowdwarves, a space for a catapult aimed at the entrance, fortification.
Then I remembered I started this fortress on an island. Surrounded by what is either a small sea, or a big lake. Which is in turn surrounded by mountains. I suppose if I tick off the civilisation the settlers came from… or a dragon attacks… it’ll be useful. Otherwise, all those five-glass-serrated-disc traps are just there to look pretty.
