My lair at Tea on Drakul has upper t1 and t2 work with coin on it (has been for I think years now). It is hatchling accessible, take the Kir'ignat portal that in on guild portal list. Go west and curve around to the frozen waterfall and drop down on the north shoreline. When you reach the pool of flowing water you will be at Tea, lair is named "The Retreat_Study in Fire & Ice". If you need attunement to Kir'ignat see Valkoth the Ancient at Dralk, greet a second time after you get the quest and you are done.
Let me know if you decide to work on it and I will get you on the permission list for storage access. There is a set of t4 machines and vault in there. Work is on the grand hall. Hatchlings will need to recall to leave, at least I've never found a land route back up to the gate.
- 152 units Viridian Lattice
- 251 units Rough Flowstone
- 218 units Mild Excoriation
- 93 units Cerulean Lattice
- 142 units Flawed Maelstone
- 164 units Flawed Flowstone
After that the work there is t6. If you really want something else to work on I have another grand hall at Serenity owned by Caliginosus. That one doesn't have coin already on it, talk to me if you want to work there and I can put some coin on it.
