It was already past 5pm when Rocky entered the main premises which was why he was not supposed to partake in any activities for the day.
Through talking with Nubi, he realized that there were 4 other individuals in here with him right now, however, only one of them was a snake-men.
Apparently, to save the clan from complete extinction after the snake-men ancestor ascended beyond the tower, the previous snake-men clan leader had made alliances with various religions to use their ancestral hall once in a while in return for a defense agreement.
Despite owning the hall, the snake-men could only send 5 of their young ones inside every year as all the other slots were pledged away to various forces, which was why Nagini giving away one position to Rocky was that big of a deal.
She had prioritized giving him a slot over the promising young of her clan and had done so with no immediate benefit in sight.
