RTF is a global modification that replaces all towns in the game.

1) Has anyone already translated the names of the creatures for the Sanctuary? (If not, I'll translate them myself)

Yes

2) What should we call the racial skill for the Sanctuary?

I'm not sure, something like "contemplation" or "self-improvement" - that is, the more Haven creatures fight enemies, the more they "understand" them (find their weak points), which allows them to deal critical hits.
