How would you do a Cthulhuesque space opera? Cthonian Stars offered some good ideas, however I think a battle between the Zarr and a space force of humans. The horror aspect would be when humans get on the ship and find out about how far removed from nature these things are and that their ships and powered by occult forces. How else would one do this and what alien races would be good to use? The Migo would be a must.
