Vestec, Sin, and Lazarus have more or less covered those four themes between the three of them

Since you're struggling, I'll help you with a few ideas that should be interesting while not intruding on anyone else:
1) Death(Plague)
2) Water(Ice)
3) Revelry(Cannibalism)
4) Wilds(Forest)
5) Ice(Stillness)
