To get to the link you need to search "Start as a vampire" on steam workshop. I cant post links.
Now, you can start the game as a vampire!
The vampire is an argonien and you have the vampire options. But, you cant be a regular argonian after choosing this race at the begining. Its a regular race of the game. Let me know what you think 
First version: 0.1
Currect version: 0.7
VERSION 0.2:
Now you can also open a Khajiit vampire. I'll try to put a human race (like Nord or Breton) as soon as I can.
VERSION 0.3:
Now you can also open a High Elf and a Wood Elf. There is a known bug that the game crushes randomly while choosing a wood elf or a khajiit. I'll try to fix it as soon as I can, but it does not supposed to stop you from opening a vempire (it happents sometimes, not all the time).
VERSION 0.4: Bug Fix
**How to fix the crash bug: I know it seems syupid, but it works. I have fixed some parts in the bug in the last update (21 june) but if it still doesnt work, You need to "jump" the the REGULAR wood elf and than choose the vampires. Than it supposed to work. If you dont understand, watch the video. You can see it there.
VERSION 0.5: New race added: Dark Elf Vampire.
VERSION 0.6: Start as a CHILD Vampire!
VERSION 0.7: Your vampires, from now are NOT the same vampires as regulars. They have 2 new spells of illusion. Strong and effective (Not OP. If you think its OP, tell me and ill change it). You can see the spells under "Illusion" after choosing the race. I'll add more spells soon.
**If you have already opend a vampire, its ok. You will get the spells
I Hope you like the mod.
