*Since the days from their first appearance at Cavendish Hall, the frog monsters have been increasing in number. In an effort to tie up loose ends on an old mission, Kate Corrigan wants to make sure that the first frogs that B.P.R.D. encountered were truly dead. Abe has given up field work, and refuses to lead the mission, so Roger is chosen. Roger takes his field team to the sunken ruins of Cavendish Hall, where they find and confront the former Cavendish family members whose humanity is far behind them. *Source: Warlock
**As the frog cult spreads across America, Roger the Homunculus returns to the site of the B.P.R.D.'s first clash with the frog creatures--the ruins of Cavendish Hall, where Hellboy, Abe, and Liz first encountered both the frogs and Rasputin (Hellboy: Seed of Destruction)--to track down the final pieces of the puzzle of the Cavendish family. **Source: darkhorse.com
