Yutai

From Demiurge Games

Yutai, Plague of Ti-Lung is a rat looking plague spirit that once infected the water dragon, Ti-Lung. Insinuating itself within the pattern of the dragon, the spirit corrupted its form, diseasing it and spreading its taint to the villagers who drank from the dragon's well. Only when Dewei and Vivian arrived and began to surgically attack the dragon to free it from Yutai's control did the plague bane detach. Latching on to Dewei, the spirit entered the mage's mind and began to wrestle Vivian for domination. Yutai didn't notice what Dewei was doing while engaged with Vivian, and only came to realize its predicament as it was being sealed within the Book of Silver and Jade.
