Windmirrors is full of engravings of a legendary dragon incinerating and otherwise killing elves in the Desert of Riders where the fortress is located. Then, during an operation to do some magma casting a dragon suddenly appears to the west! Is this the legendary monster come to visit fire and destruction upon our fortress?
Turns out that it is not. Ustra Anstrideve Abliusmok Lelgo is his second cousin's twice removed former roommate. But it's a dragon in any case - so the various hatches are sealed, militia is readied, and spike traps levers manned.
The dragon charges right for the south access tunnel and goes in. He crosses a narrow bridge while training weapons, wooden weapons, and a few spiked balls rain blows upon him causing bruises and chipping scales. Two-thirds of the way across a serrated bronze disc gets his attention with two hits causing internal organ damage and a serious leg cut. He opts to dodge the third attack - into a pool of magma below. A pretty anti-climactic end I think...
Which, he being a dragon, has no effect. And since the pool is full he swims to the end of it and climbs out. And continues up the tunnel with some of his wounds apparently healed (cauterized by the magma?). More traps are there - serrated glass discs glance off his armored scales as he turns right into a smaller tunnel.
And right then...
The spinning (iron great axe) strikes The Dragon in the head and the severed part sails off in an arc!
Time to put the engravers and statue makers to work! The mechanics get this one built in their quarters!
Or we'll just preserve the head and let them have that.
