Vale of the Mages (3e)
The Vale of the Mages houses four wizard's towers. A river forms a 'Y' through the vale's cliffs and woods. The first tower is a classic old and cozy round wizard tower; a small three-storey building constructed with smooth river rocks. The tower features all the necessary for a wizard and an apprentice; a small laboratory¸ a kitchen¸ and bedrooms. The second one is a larger square tower¸ it's perhaps a tower built to house more than one apprentice and for a more ambitious sorcerer. The third one is the largest tower of the vale; perhaps it is an archmage's tower. It features a large garden surrounding the main building¸ stables¸ a small dungeon and a central six-levels tower. The last tower is a ruined one; few things remains of this ancient round tower¸ but adventurers will find for sure something for them!
"You can use the vale as it is¸ with all the four towers together or use each tower singularly¸ as best fit in your ongoing campaign.
