The Green Tower
The Green Tower is an enormous megalith of serpentine wrapped in vines thicker than many houses that string between a circle of enormous oak trees. It is the largest Tower by far, both in its own physical size and in the lands that it controls; the Green Lord, Sol’Vander, has embraced the wild and the untamed, and is arguably the single most powerful of the Elven lords. The Green Tower is the most violent and the most hostile of the Towers; its tenuous alliance with the Grey and Bone tower is founded on absolute necessity, and Grey and Bone maintain their relationship almost solely out of fear that if they separate the Green Tower will swallow them whole.
The Sacred Grove:
The Sacred Grove is actually much less important for its sacred nature than for the experiment Sol’Vander is attempting there. An enormous serpentine stone has been raised, and some five centuries ago the Green Lord began attempting to construct a second Tower there. It has since come under major assault nearly four dozen times, and the continuous and violent presence of the other five lords and their specialized brands of magic has prevent his efforts at Tower-building from getting very far. The air here is so powerfully charged with magic that only the six lords can cast spells with any guarantee as to the result; many battle plans on both sides have gone desperately awry due to spell failures.
