This month's June/July challenge is to map a multi-storey villain's lair. This could be anything from the classic necromancer's tower, to a many leveled zeppelin or flying castle. The only requirement is that it have more than one level and that it be used for nefarious purposes.

This should be detailed enough to use as a reference for combat encounters but it is not required to be at a large enough scale to be printed out for use as a battlemap.

This challenge will be closed on the 15th of July. Happy mapping!
