Minecraft medieval fantasy tower, 1...

Minecraft medieval fantasy tower, 11x11 circular base, highly detailed, professional builder style. The tower is made of stone bricks with variation (cracked and mossy), with strong depth using stairs and slabs for shadows and texture. In the center of the tower there is a vertical magical energy core made of blue stained glass, with a hidden light source behind it (sea lantern), creating a glowing blue effect (not a beacon beam). The glass is slightly recessed to add depth. The core is framed with darker blocks like obsidian or deepslate to increase contrast. The tower walls have small medieval windows with iron bars and decorative supports using dark oak logs and trapdoors. The top of the tower has battlements (castle-style merlons), alternating blocks and gaps, with extra detail
