Seven

Bungie has used the number 7 repeatedly in its games as well as in the surrounding "Bungie mythos" (e.g. the 7-Step World Domination Plan). This numeric theme extends to powers of 7 (49, 343, 2401...), multiples of seven and numbers that add up to seven somehow. The number 3 holds secondary significance as a "Bungie number".

Below are a few occurrences of 7 in Oni. Coincidental or intentional? You decide.
