The Gilthar's Garden Key Quest (Adonis)
Before getting the quest, it’s faster to get a quest item as it saves you returning to the temple twice.
1. Get the note
Adonis city – NW of City South garden exit 1601 x 908 Adonis City. Look for 1st note drop and 2nd note drop green dots
Both portals lead you to a mob either Jorr-Thrak Dal or Urga-Yutt Dal that drops the quest item - a Note. But as the drop rate isn’t 100% & they’re on a 20 minute spawn, you might need to kill both at least once.
2. Get the quest!
Head to the Redeemed Village Acropolis. Come out of the Outermost Yard Garden Entrance and its to the NE. As always with temples, into the second room & up the long staircase. Take the South door & speak to Ecclesiast Gill Jha. Talk to him & get the letter. The guy standing next to The Ecclesiast is Sipius Gil Ilad-Ulma. Talk to him & show him the Letter.
Return to the Ecclesiast Gill Jha and show him the Note you looted from the unredeemed mobs mentioned in part 1.
The Ecclesiast says something like: "First you should locate these Arks mentioned in the note. I have received word from the Acolyte that there are two Arks. One is standing on a platform and the other is wrecked, with parts spread all over the area. You must find both. Then take the note you have brought me, and give it to the Diviner, Gil Ulma-Duna, in the Garden. He will tell you more, and tell you how you may aid the Diviners. For now, take this insignia. You may offer it at the statue of Gilthar to gain entrance to His garden..."
3. Tag 2 devices – see image below
You have to go to 2 crashed looking ships – one is at 2802 x 2533. Looks like a black spaceship. There are some spirits that are aggro. Inside, in the middle of the ship there’s an Ancient Control Panel. Target it & you should get a new mission. The second Ancient Control Panel is at 1671 x 3023. Target again & then you’ll be asked to return to the garden.
4. Return to Diviner Gil Yeol-Ulma
Return to the garden – talk to the diviner (near the shops) and you’ll have a shiny garden key!
Continue the conversation to start the sanctuary quest.
Thanks to other forums & SL Atlas for the knowledge to let me get my key! Plus of course Cerbs help
