CAS stands for Create-A-Sim like when you go into the game and create a family, it's called the Create-A-Sim screen (CAS).

It is real I think but what it is, is probably two or more scars put together which can be done in CAS.

There's something similar here. (Must register to see) You can see the sim here without registering.

The slit face may be a stackable face make up or found under the foundation section of the regular make up for sims. Sometimes people combine a number of facial scars together. You may be looking for two or more different effects put together.

Also, as I have asked you more than once before, when making any request, provide links and pictures.

@TheNPCSim -- Not letting you in how? What sort of error are you getting when trying to load the site? What url are you typing, or link are you clicking? Garden of Shadows is working fine for me, albeit somewhat slowly. Can't figure out much here for you without any information from you.~

Is it trouble registering? If so, do know that you don't have to register at GoS to access the downloads (Hell, I've been lurking 3-6 months now), since all downloads from any thread are located on fileshare sites & aren't restricted to members. If it's the downloads from those sites that are not working for you, try one of the "mirror"/alternative upload links most users there provide, since popular files' monthly bandwidth can be devoured faster than a buffet in the hands of Fat Bastard.

If the website itself will not load, try clearing your web browser's cookies and your internet traces/cache (Cache Clearing for PC Firefox 3 -- A) Taskbar @ top: Tools > Clear recent history... > Time Range: Today or Everything > Details: Cache [leave rest UNchecked]). For more details on Browser cache & history clearing, try your respective browser's website; there should be info, if not tutorials, there. After that's all squared away & your browser's all chipper and squeaky clean, try reloading GoS. If it still will not load, there is a chance the site could be down for maintenance, experiencing  an error/host crapshoot/other LOLZ@U by the internet. In that case, I'd suggest waiting a few hours to a day & trying again a couple of spaced-apart times. If then it is still not letting you on, you could try contacting a GoS moderator here or on another site (ie, some use MTS). If you haven't been banned (either temporarily or permanently for past behavior onsite), then you could try politely (** and grammatically-correctly - they don't take kindly to chatspeak, smiley abuse or colored fonts! **) messaging one of their moderators who stroll into here/MTS on occasion. I can't say -now- who that'd be (it's been ~4 years since my last login here OTL), but in the past, liegenschonheit, Ghanima Atreides, Jenfold, Nymphy, and a few others were folk I'd seen here and/or at ModTheSims before I'd ever even heard of GoS.

Bear in mind if you or -anyone- on your router/network/household has been banned from GoS, you won't be able to access the site (kinda the concept of bans, after all), since your IP (your internet ID) would have basically been blacklisted. If that is the case, sorry dude, we can't help ya there. :/

Alternately, if you just want a general pale skintone, try any one of the [expletive]TON of skins Enayla uploaded here and at MTS, or the Louis#7 skins by Louis (user: Ren) @MTS//any Louis#7 Lin Edit. For that matter, check out Ephemera's skins (google or look here/MTS~), since it appears from posts above that EP/Ephemera was the creator of the skin in question; in particular, try the SimpleSkins set, as the pale looks fairly similar, if I'm not mistaken. There really are a ton of pale skins out there, if you're just looking in general. ;P
