Atelia Fortress good luck aggro mobs that hit hard go with iss with DM up
The Aden Vanguard captain Adolph tells you that Glenkinchie is in Stronghold I. He said to defeat the Embryo in Area 1 in order to gain Glenkinchie's trust.
In other words, go the place on the map where the quest shows and kill the 4-5 mobs that you will find there on this kind of platform.. After that the NPC (Glenkidish something) will appear...
I had the same problem until i understand how these quests work..
You will need a party of course to kill these mobs.. You can never do this alone.. Alternatively, you can monitor the place and wait until some other party does the killing for you..
