In case you're wondering the meaning behind the bad joke, it's a play on the flavour of crisps: salt and vinegar.
But with that out of the way, heya! A while back, ValkoorTheVictorious made a post using anagrams of related words (specifically, companion names). I loved the idea and had this idea on the backburner for a while, and here you go. In case you didn't know, the Vigenère cipher is an encryption method using a set of interwoven Caesar ciphers, all based on a keyword. Well, I'm actually giving you the keyword: "pirate". You can use a decryption site if you'd like, but I would encourage you to decode these on your own. However, rather than these be companion names, they're the names of worlds. Here they are:
Hslle Mhtrnw, xwm falmh.
Ufnjyxaka, mlt pflr ppvu.
Vtptvtit, ppvu oy wiwimr wzqvs.
Vsdt Iaggw, bye pmal wrhriqvr.
FsdAyu, mlt jvanxxnll cesm.
Dakptgsogi, ipv gkipb vmimgm.
Rqnmai, cagh dn xoww.
Don't feel discouraged! I admit my explanation on the cipher was bad, but it's easy to understand. It's not hard in any sense of the word. Cheers!
