Don't know latin in any way shape or form. Just was curious and used this like a small puzzle. Added a bit more context to words that weren't very self explanatory.

    TOTUS - all/whole

    VESTRI - your

    ARCANA - secrets

    NOCTI - night? - 'used in formation of compound words' [0]

    NOBIS - us/we

    EST - to be - "can be translated as 'it is,' 'he/she is,' or simply 'is.' It is the third person singular of the present tense of the verb 'to be'" [1]

Sooo my guess would be something along the lines "All the secrets of the night belong to us?"

If someone knows any better I would love to be corrected.
