As companions try their best, most of their pillars surrounding small grove light into life, runes on them blazing into warm greenish radiance. However as Martelai meddles with one of them, it seems that effect was contrary to expected as pillar only hums softly and two other power down.
As pillars activate, pale radiance in warm shades of green and golden surround the grow, light radiating warmth and sense of safety.
However, bubbling in the swamp grows in intensity and with creaking sound of splitting earth and breaking roots, cracks appear around the grove and clouds of foul, grayish mist surge from them, stinking of long dead corpses. This foul miasma forms into vaguely round clouds which seem to have life of their own, forming tendrils reaching toward nearest living thing.
At the same time, ground rumbles and with shower of fetid water, massive vines burst from below, strange things resembling tendrils of some alien beast, but wrought of coiled vines fitted with enormous thorns rather then flesh. Things coil and weave and seem it is obvious they have mind, or at least will, of their own - claw-like thorns probe the air, turning toward source of heat and life as things extend themselves from cracks in the ground, each well over 9' long.
