I don't quite know the full background behind Ohnar West's grievances with Cathay as recently aired on the rulers' forum
Wait, what? We have grievances with Cathay? I think Veleno has to give Selene a talking to, just as soon as I find this out IC. Cathay has always been a useful ally to Ohnar and Lasanar before her.
EDIT: On the rest of what you wrote - interesting. I wasn't overly aware of the southern war, but it seems something Veleno would be interested in if Batesaor is involved (she has a soft spot for the city). Otherwise, she's too busy with northern politics to be overly bothered unless she's sent there as Ambassador.
