Out of the dark mists of gloom (aka "bloodsong's brain") comes this dire prophet of doom -- the StormCrow.
This shoulder pet has a hunched countenance and beady blood-red eyes. He has a whalloping 50 doom/goth/macabre sayings, plus you can add your own. (The script will also check any sayings you add, to make sure none are too long. This bird can wax poetic at times.)
Randomly (or on command, if you prefer), he will emit one or a series of caws. And/or a dark stormcloud will appear overhead, with flashes of lightning -- complete with light and sound effects. (Warning: when zoomed in, the sound may be quite loud. I did turn down the volume in the script!)
Customizable (including the script), and transferable.
And remember, Halloween is coming.... ;)
PS: NO, he does not EVER say "Nevermore." Too cliche! ;D
