After all, how would they know whether he had it or not if he didn't expose the fact that he traded it for a favor?
If it was able to kill even race leaders or beings above them, then he would never trade it with anything else.
Alas, he had no use for a weapon that was capable of killing those within his own reach.

After the ceremony ended, the teams were told to join the after party if they were interested in participating.
Felix was planning to pass on it since the primogenitors would be having their own separate after party.
Instead of wasting his time in it, he went to take a long night of sleep after being awake and active for three days straight.
