I'm pretty sure there's no secret back entrance for the elves to exploit this time. I mean, I hope.
Look at that bad boy. Seriously, fucking click that shit. So large it ain't even covered in the picture. The Wall is two layers of stone deep - twice the strength of the tower itself - and, so far, two Z-Levels tall. I might go for three tall, because why not? It connects to the mountainside north and south of Stesokur Tower, and I made certain that there's no way any damn elves are gonna sneak in the service entrance. How can I be so sure, you say?
"Everything's already covered in blood." - A common saying in Stesokur
This is the mountaintop above the wall. Remember, the elves took advantage of a hidden slope that I had missed, like a goat path or something, and then literally walked along the top of the walls, and down the stairs into the heart of my last fortress. This time, though, I built a wall - again, twice as strong as necessary - literally cutting off any foot traffic to the top of the wall. Even if the elves found a way onto the level behind my wall, they wouldn't be able to find a way down.
Which means that there is literally one way into my fortress:
Maybe I should just name this area "The Zoo"?
Those green symbols, pointing upwards? Those are cage traps. A small army could be trapped in those motherfuckers. I've got more, lining the entrance into Stesokur Tower itself, but so far I haven't seen anything get by these traps. I can't wait to piss off some elves!
