Luckily derm is standing in it or that other E rune would have prevented it from activating. Again.
The Rune hovering above derm's head counts down to E1 and then finally vanishes. The entire circle glows and the courtyard shudders with immense power. The separate levels of the circle begin to rotate in opposite directions and magical discharge leaps from them and pours into a point a few feet above derm's head. A point of light appears their and quickly balloons outward, forming a silvery, molten ball. It expands further and further, becoming more opaque as it does until a sphere nearly 20 feet in diameter hovers just above the ground on which the circle is inscribed. It's surface slowly undulates and those outside can see within it as though they were looking through the surface of a pond at what lay beneath: it's hazy and distorted, but it's there. They see great green masses a black expanse.
Derm on the other hand, since he was standing right in the center of the damn thing, find himself standing on the stem of a leaf. The stem is easily 10 feet wide and and the leaf itself expands out in front of him like a vast, hanging platform hundreds of feet in width. The leaf is affixed to a branch, which is further affixed to a tree of simply incomprehensible size; miles tall, with boughs that stretch to infinity in all directions, lost in the distant fog. Below, at the tree's base, is a great black sea that spreads to the horizon. The air here is so thick with alcohol fumes that it's not only enough to make him cough and choke as though he were breathing smoke, but it's rapidly getting him drunk.
