How come the Cats didn't have full control of any worlds? Wasn't that pretty rare among the Clans at the time?
IIRC, not having one Clan have sole ownership of a world was established by ilKhan Kerensky by design. He wanted them to fight each other and be dependent on one another. That said, by 3052, some Clans had full control of planets, notably: Burrock (Albion), Coyote (Tamaron), Fire Mandrill (Shadow), Jade Falcon (Kirin), Star Adder (Sheridan). And in some cases, Huntress, the Clan owned all but a tiny percent of the planet.
As far as Nova Cat holdings go, and it would be interesting to look up what is on these planets, we have:
- Barcella (55%) - Nova Cat capital
- Bearclaw (20%)
- Brim (20%)
- Circe (20%)
- Delios (30%)
- Gatekeeper (40%)
- Hoard (30%)
- Lum (40%)
- Strana Mechty (6% - like every Clan)
The Jade Falcons and Diamond Sharks had a few more planets than the Nova Cats, but in some cases with significantly smaller stakes (Jade Falcons owned 2% of Huntress and 5% of York). The Sharks are by far the largest, but the Nova Cats come second. And, as I think was mentioned, we had a special relationship with the Sharks, our closest ally.
I've also always thought it odd that we own no part of the homeworld of our totem animal, the Nova Cat of Dagda. But maybe it was decided that Dagda wasn't worth holding.
