Last reply is the most well-sourced: In short, according to official Dungeons & Dragons sourcebooks, powerful wizards often live in towers because they can create towers quite easily using magic, and have need of a highly defensible home for reasons of security and privacy. They have many valuable belongings which they need to protect from theft or harm, especially while they're away. They often undertake long periods of research or item crafting where they don't want to be disturbed, and often have enemies or rivals who want to attack them or steal their magical research or items. They may also wield significant personal and regional power and require a base of operations from which to control the local area. All these things necessitate a defensible home, and a tall tower or castle of some sort is a time-tested solution to this. https://rpg.stackexchange.com/a/196562 https://rpg.stackexchange.com/a/196562
