Menhir Stones are components of a magical device or location. Arranged in a specific pattern, they can be used to create various magical effects. (An example of such a thing can be found in DMG2 117-118)
The Ancient’s Great Circle
They have a number of known traits:
- Magical Transportation to other Menhir Stones or Ancient Transport Devices.
- Remote Senses (Luckso, via experimentation, was able to see from one site to another).
- Spellcasting – When the Addershade Mehir Stone was first encountered, a giant spider was summoned from it.
- Activation – The party (and possibly ‘The Halfling’) have been able to ‘activate’ the previously inactive stones. Doing so, they are greeted by an Ancient Message.
