I asked emp about it and he said if a cannon bio has no KG and if its real clan is unknown u can make him a part of a custom clanHave you got permission from Nexus for lvl 2 now? Otherwise remove the booster things etc.
But there's something I need to now first. Originally the only custom clan was Kiyoshi, but now due to the Mandalorian clan people start making a lot of bio's with that and I'm not sure you can actually mix canon characters without clans and custom clans.
Before I find that out I can't approve bio's that mix those two.
