Solen Matriarch Quest
The Matriarch of the Solen is located at the center of her hive. If she will not speak to you, give her a plant seed to be offered her quest.
She first requires you to kill 7 enemy Solen Infiltrator (Warrior)s and/or Solen Infiltrator (Queen)s. If you started in the red hive you must kill black Solen on the same Facet, and vice versa. The red Solen hive is in Trammel, while black Solen reside in Felucca. Infiltrators can be found outside the hives in the mountains north of Britain or north east of Vesper.
Next she will request that you refresh the Solen water supply. It is recommended that you collect 8 pitchers of water before you head back after killing the requisite Infiltrators.
Once you've emptied the pitchers into the vats located at the south-end of the Solen Hive center chamber, head back to the Matriarch. She will ask for 200 Zoogi Fungus (which you'll hopefully have collected during your previous hunt). Upon receipt, between 250-350 Gold and 100 Powder of Translocation will spawn in your backpack.
You will also no longer be attacked by members of the hive, at least until you start attacking them or befriend the hive of the other Facet.

Additional Details
The Red Solen Matriarch quest is started by talking to the Solen Matriarch. She is found in the center of the Solen Hive.

However the Matriarch is not too willing to talk to those she doesn’t know, so if you do not hold her friendship you will have to offer her a small gift in order to talk to her.
Luckily the Matriarch has a weak spot for plant seeds. Give her one and she will offer you a chance to gain the friendship of the entire Solen Hive.

The Matriarch will give you two small tasks to complete in return for safe passage through the Hive and a little something extra. The first is to kill seven of the enemy Black Solen Infiltrator (Warrior) or Black Solen Infiltrator (Queen).

To find the Solen Infiltrators, there are three places you can go. The entrance to Wind, the southeastern part of the Trinsic Jungle and the Windemere Woods northeast of Vesper. At those places you can find both Solen Infiltrator Warriors and Queens, both kinds will count, so just kill seven of them. While you are killing the infiltrators you might as well collect some Zoogi Fungus from the corpses, so you have something for the Matriarch to convert when you’re done.
Once you’ve killed seven of the infiltrators you should go find 8 gallons of water to replenish the water supply with, a normal glass pitcher holds about a gallon, so you’ll need 8 of those. Pitchers of water can be bought from most Innkeepers if you don’t know anywhere else to get them.
Now return to talk to the Matriarch and she will tell you what to do with the water, pour it all into the large vats in the southern part of the lair.

Once that is done, go talk to the Matriarch again and she will offer to convert some Zoogi Fungus to Powder of Translocation for you.

She will convert up to 200 Fungus into 100 Powder. In addition to the conversion she will also give you a few hundred gold pieces and make sure none of the Solen on the facet you’re on will attack you, at least not unless you attack them first.

Note this quest can also be completed in Felucca. There you will visit the Black Solen Matriarch and kill Red Solen Infiltrator (Warrior) or Red Solen Infiltrator (Queen).
