Read All The Books Aaaaaah! discussion

I'm learning things from this book. It says:

There was a high tower at each corner of the stockade, but unbastioned, and he judged that the Albs had not yet learned that trick of defense.

What does that mean? I thought a bastion was just a fortification. Well, I looked it up, and it specifically refers to the projecting part of a fortification. So, the tops of those towers that extend outward around the edge, where the enemy can't shoot arrows at you or see you, but you can drop things on them or shoot at them through holes in the floor.

bastion never fails to make me think of Hollow Bastion from Kingdom Hearts and nothing else

The thing that comes first to my mind is the game titled Bastion, but yeah, Kingdom Hearts too.

that looks cute
