Description
The now ruined Duke’s Fort held out for as long as was possible given the size of the invaders’ force. But they came with such force and ferocity that even the well-trained soldiers and the supreme quality of the walls could not hold them back. Brick by brick, it crumbled, and the peasants and nobles alike inside were slaughtered. What the Count found when he rode to aid the Duke was nothing but a smoking pile of rocks.

See below how the Ruined Duke’s Fort tessellates with the Castle Walls. NOTE: to achieve this, you’d need to use the “Ruined-Dukes-Fort-Small-Square-Bastion-A” on all four corners.

Loving the whole HEX system.
Request: bent, like broken in, metal and wood doors for the whole system (and other ruined buildings you’ve made). I know it takes time. No hurry. Keep up the great work!

The info about tessellation is always very helpful to understand how to integrate a given set into my whole setup. however, for this set, there are “I-Adaptors” mentioned as one way to connect the fort to regular walls. But in my download I cannot find the adaptors, I think. I see the mentioned B-F and B-M adaptors and the only other connectors to the wall system are H-to-Female-Gate and H-to-Male-Gate connectors. But I think they are not the same as the I-connectors, right? Can I find them in another set?`I looked in the Ruined Walls set, but that has no adaptors at all.

The I-Adaptors mentioned are in the Tower Connectors Walls folder. They are I to B connectors.
