The multiverse is very small after all and you have a lot of siblings. You will encounter other Entities in your travels more frequently. If you settle somewhere for a period of time, one of your annoying relatives will drop by for some conversation.
The Entities you meet are not all hostile, some are friendly and will share DATA and a few loners will answer your BROADCAST with silence. There are however predators out there, be prepared to fight or flee.
If you have Infection Detected most Entities will be hostile towards you unless you are careful about concealing your identity.
