Some things to keep in mind
I would say the Shiva Keshik's paint scheme is Pure White with Black Accents
The Purifiers is white with steel grey panels or quarters of their mechs.
The Omicron Galaxy was Steel grey with white panels on their mechs.
Omicron Galaxy may not be the same as Omicron Cluster.
Omicron Cluster is a Clan Sea Fox unit that decided to stay behind. Omicron Galaxy was hashing it out in the Republic. Another fun thing from the Uniques pdf.
As a Clan, the Spirit Cats follow many rituals, many of them far different from those of other Clans. For example, in the Ritual of Battle (held before a combat), Spirit Cat warriors meet around a bonfire and tell stories of past battles won and combat to come. This ritual is also performed by warriors of Clan Nova Cat, from which the Spirit Cats were born.
