Calamity helped Jessica and Xanthos put quite a few lillies in a large container along with at least three liters of the disgusting green sludge that filled the lake. She also helped them cover the glass container with many sheets of blankets so as the lillies didn't get any light but that strange purple glow.
"If they get ANY light, they will all die instantly," she informed the two compainions as she strapped the container onto Xanthos' belly where it wouldn't get hit by his knees when he ran.
After they had the lillies safely strapped on and had said their goodbyes to Calamity, Xanthos began to run down the tunnels again listening closely for Jessica's directions of which turns to take.
