Beacon Tower - Walls?

[SpacialKatana]

Can anyone help with the Beacon Tower?

Namely how to do the bottom part, which walls to use. The castle walls I've tried dont seem to line up >.<

I've found the furnace you can place inside for the gems though

Did you use castle wall entities or tiles?

I thought it would be castle walls, but if they don't work with the surrounding tiles then you might have better luck building the room manually from entities.

It's not complete, but I guess it's better than nothing for the start. Link
