There are 3 levels in the stands. There's the topmost level for the interaction of gods, the second level for demigods and divine lords, then there's the third level for the mortals. It is based on the social hierarchy of giants of order and because of safety.
A mortal being around so many gods can be very dangerous even if they are only there in the form of their avatars. A mortal might hear something they shouldn't hear or join in laughing at a joke made at the expense of another god. So it is best that you stay clear of the divine as a mortal to avoid the destruction of your entire family.
Helios found a seat on the third level and sat down. His guards surrounded him and prevented others from reaching him.
"Thank you for coming. Please have a good time. Continue as if you haven't seen me." He said to the excited crowd.
