Kael didn't really need to discuss much with his group about his plan since they didn't really have one.
All of them were new to this area and had no clue about it. So they were just going to randomly search for some medium-range Beast Tribes.
After all, they couldn't afford to offend any of the bigger tribes. Any of them would easily crush all of them... well, maybe not all, considering they had Rias with them.
But Kael didn't plan to use her for obvious reasons. Even if he went against his conscience, there was no way a Demi-God could remain hidden after acting.
Rias was already an anomaly for moving around without alerting anyone, but if she truly acted, Kael was afraid it would alert other factions.
And they weren't strong enough to face any of them.
Besides, if he used Rias to get work done, then it would only be a nation formed with fear. He didn't want that because he neither liked it nor did his Ultimate Skill allow him to do that.
