These are Trix's Vampyre Grendels with the CFE edits applied. Nothing more, nothing less. :)

Sprites not included- all necessary files for the breed to display properly are available (at the time of this writing) from The Universe of Ettins. Genome uploaded with permission.

Known issues: I used a grendel caption file when editing as the breed didn't come with one, so some normal norn genes show up as <no caption> in the Genetics Kit.

To install:
Put gren.cfe.vampyre.gen and gren.cfe.vampyre.gno in your Genetics folder, and inject into the game by the means of your choice.
Put the starter pair of .creature files in your My Creatures folder.

To use them with the Vampyre egg agent:
1. Backup the original gren.vampyre.gen and .gno: move them out of the folder or rename them to something like old.gren.vampyre.
2. Rename gren.cfe.vampyre.gen and .gno to gren.vampyre.gen/.gno and place them in the Genetics folder.
3. Muco will now produce CFE Vampyres. This may require you to have had Muco lay at least one normal egg first, I'm not sure.

Enjoy!
