Tower for Pale Garden

Structure: The Pale Garden should have a structure, but it shouldn’t be any small structure like a witches hut, a or an igloo. The structure in the Pale Garden should be a slim, but tall tower, it doesn’t have to be wide or contain too much. The tower could be an amazing sight to see from distances and using blocks that would fit the theme of the pale garden could make it even better. Loot: Maybe if you climb to the top there could be a reward? Silk touch enchanted books would be great for that biome, so you can collect the Creaking Hearts.
