SA peerless question

[Fermi]

if I open the the door to the peerless with either eggs/orbs can anyone go in or must they be in my party?

All members of your party will receive a message and be asked if they want to enter.
They can refuse but if they accept they'll enter with you.

Other people who are not in your party won't receive the message and won't be able to enter.
