Scioly Assassination 98: The Most Dangerous Game

[Cheesy Pie]

Clue targets Forever. The first letters, read top to bottom, spell out forever.

I protect forever physics because of the reason stated above

The only connection I can find is that all those people were born in the late 1800's and were active up until the 40's.

Bump. Wow, never seen an active Assassination game on the SECOND page before...

[Littleboy]

I never want to again. EVER.

There hasn't been a post with any meaning in it for over 2 days.
I feel the sassy is probably inactive/forgot about this game. Sassy? You there?
In the meantime, I suggest you looking at who hasn't been on in several days and make a suspect list off that.

The Sciolyans, to my annoyance, are still celebrating the beginning of 1943. Perhaps that is why only one protect was made. No matter. Your next clue shall be harder. I may even claim another victim.
Annoyed by the extended New Year's party, I attempted to slip hydrogen peroxide into foreverphysics' sparkling cider. I watched him drink it, and awaited his death. Instead, I had the disappointment of watching him immediately spitting it out. fozendog must have snuck into my room and switch the vial out for water. Disappointed, I write these 3 codes:

All use different ciphers. One doesn't need a key. Another needs 2 keys. No key will be repeated. You have 2 days. Good luck.

An ID clue has been given in this post.

[mnstrviola]

not sure if sassy knows forever's a girl or is just trying to trick us.

ahh ciphers

The middle one is a base64 encoding, it requires no key, decrypts to http://uploaqžwikimedia.org/wikipedia/commons/4/4b/Apple_pb.jpg

one misspelling, the q and missing . after it. I'll add the others as I figure them out.

I'm convinced that they're all urls, most likely images. The first one is probably something akin to a skip cipher. The last one is more likely something similar to playfair, where double letters don't repeat.

The last encrypted message uses the Gronsfeld cipher and the last 2 keys to get: http://web.3bir.com/7rof/e/7rf%20E%2012.jpg

I will edit this post if/when I figure out the first encrypted message.

Edit: I haven't figured out the first encrypted message, but I believe that it is some form of a transposition cipher, since the colon is in the wrong place and the part before the double forward slash is too long. That would mean that all of the original characters are there, and the key only determines how they were ordered.
