You will need to find a side mission called “Legacy Left Behind” instead of A Family Legacy. The latter name appears over the HUD after you start the mission, and the prior name appears on the map.

If you go south from Blackfell, you will find Evergreen stronghold. Northeast of this location is a house where you can start the location. A blue marker also appears on the map indicating the quest location.

The goal here is to enter Mae’s old house situated in Evergreen and find the information she left behind. This is a level 32 side mission but since Evergreen is in the Red Sands region, expect to encounter level 40+ enemies in the house.

A chest will appear as you correctly align the cubes in the Once Human Family Legacy quest. This chest will contain a Rosetta Researcher’s map. A closer look will reveal the location of the facility, which is found in the far south of the Red Lands region, near the sea.

When you open the map, you will find two large buildings with multiple floors matching the map marker. The building you need to go inside is ‘Rift Anchor Alternate Reality Research Institute’

You need to find a specific chest inside this facility. After going through the front, you must first reach the second floor by taking the stairs.

After that, you will find another series of stairs going all the way up. However, you will come across a lift with a ‘Rosetta’ label at its top. This path diverges into left and right, with the right side going up via stairs.

You need to take left here, which leads you to a different portion of the building. This part of the building is ‘R.S.T LAB’. Go to the south side of this room, and you will find a chest. Loot this chest to complete the ‘A Family Legacy’ side mission in Onec Human.
