Toothless

Toothless is the awakened (and very intelligent) plesiosaur who was the "Monster of Maer Dualdon" until the Party persuaded her to leave the people of Bremen alone.
Maddened by the boredom of being the only intelligent creature in the lake, Toothless has gratefully agreed to be available for future information gathering. She already has provided Zanborin with information on Ravisin, including her plans to awaken many more beasts to sow unrest in the Lonelywood area and drive its inhabitants to fear of the Frost Goddess Auril. Toothless has also agreed to converse with Tali Erylfok to assist in her wildlife research.
It was Toothless who sent to Zanborin, via Tali, the gift of a Emerald Water Elemental Gem.
