To join the Hunter’s Lodge in Meridian, you should have at least three Half-Sun marks from any of the five Hunting Grounds. Once you have those, go to the Hunter’s Lodge and talk to Ligan. He’ll then tell you to speak to the Sunhawk, Ahsis.
The Hunter’s Lodge leader is unpleasant even at the start of your conversation. After asking for an available Hawk to sponsor you, he’ll refer you to Talanah.
Go downstairs and talk to Talanah. She’ll then ask you to kill 3 Sawtooths, 2 Ravagers, and a Stalker then loot the Trophies from their bodies and deliver them to Ahsis. The game will tell you generally where to hunt these machines but it’s okay to hunt them from other locations, just don’t forget to loot the trophies from their carcasses.
After getting all the necessary Trophies, return to the Lodge and deliver them to Ahsis. Reluctantly, he’ll accept them and you’re now a recognized member of the Hunter’s Lodge.
