Clan & Lair
A Hard Day's Night (250)
Complete 250 tasks to unlock slots in your Hibernal Den
This one will be time consuming. You can either grind for most of the items in the coliseum yourself, or buy them from the AH. When you get stuck with many expensive items, you can either bite the bullet and acquire one of them to make room for a few more tasks to come in, or start paying for gem slots. You can trade for gems using treasure on the item sales forums, most players will offer a rate near 1:1000.
Here is a guide containing all items you'll need.
Note: This does not include the first 5 slots you are given for free.
Aaaaand... Scene (100)
Apply scenes to 100 dragons in your clan at the same time
If you want to make it easier, you can use scenes from the seasonal microholidays (i.e springswarm), since they're cheap and plentiful.
Beautiful Backdrop (100)
Apply vistas to 100 dragons in your clan
Select "customize" on a dragon's profile to see the option for setting a vista. You can pick from any that are applied to your account, and take it off whenever you want. Dragons can share the same vista. If you have a lot of fodder, you can apply them to a bunch at once before exalting.
Bug Borrowing Baron, Carnivore Caching Captain, Plant Packing Prodigy, Seafood Stasher Supreme (10,000)
Store 10,000 [food type] points by converting [food type] items in the food tab of your Hoard
If you want, you can starve your dragons so they won't be eating them while you stockpile food, but you will lose the well fed benefits. Instead, you can go to the auction house and and buy cheap food by sorting by Unit Price: Lowest to Highest, the menu for which is above the next page button.

Lots and Lots of Slots (200)
Expand your lair to a total of 200 slots
This one is also inherently time consuming. If you want to save the most amount of money, only buy expansions when your flight has dominance. If you are in a flight that isn't Earth and doesn't conquest often, you can wait until your festival, since we always allow celebrating flights to achieve dominance. Additionally, if you have a lot of extra lair space, you can buy hatchlings from the AH, wait until they are grown, then sell them for a higher price for passive profit to help bankroll these achievements.
One Big Happy Family (250)
Have 250 total dragons in your clan
It doesn't require that all of them be in your lair specifically, so some or majority can go into your hibden, which might be cheaper to expand than your lair.
Pack Your Bags and Move Away
Change your Lair's physical location on the World Map
On your clan profile in the top right, you can click the gear icon next to your lair's location to change it. All players start with two locations at a lesser lair.
Returning Home
Restore a non-progenitor dragon that you exalted
This is available through
self service, and can be done once every 90 days, only for dragons exalted in the last 14 days. It costs treasure depending on their level. If you don't exalt period, just choose one of your existing dragons and immediately restore them.
The One That Started it All
Restore a progenitor dragon that you exalted
Staff are not being cruel, you can
restore your progenitors for free once every 3 days, with no limit based on how long ago they were exalted. It will not reset your dragons level, and there won't be any kind of glitch preventing you from getting your dragon back. If something goes catastrophically wrong somehow, you can always contact staff directly for help.
What a View!
Apply a vista to your account
This can be done by going to the specialty tab in your hoard, then clicking on the vista item and selecting "apply to account". It won't automatically appear on your posts/profile, and can be accessed from account settings. Vistas are not single use, they will be there forever and can be swapped out at will.
