Here's a blog post to help you know the latest news relating to Champion of The Daedra.
I'm just looking at screenshots I've taken and rolling off some information about them.

Updated (26 May 2020)

1. I made a Carrot Cake. It's based on the Elsweyr Fondue & the Vegetable Soup. It can be crafted from 1 x Sack of Flour, and 2 x Carrots. 

2. Applejuice now has a new mesh and now restores 20 stamina, health and magicka over 14 seconds.

3. There is a new joinable faction: Trinimac Faction. They are not aggressive to you if you haven't joined, but if you kill one of the Velothi Cultists who occupy the shrine locations on the newly added Shattersky Island, you will get a killtracker added. It will count your kills and if you reach 100 kills, you'll get an invite to join the Trinimac Faction.
If you accept, you will be able to craft Trinimac Robes. These robes are available in 5 different types, based on gem types (Amethyst, Emerald, Diamond, Ruby & Sapphire). Each type will add a spell to you when equipped, which is a magic projectile attack. The Trinimac Robes have 1000 hp and a 50% reduction in the 5 schools of magic (1 school per robe), for example, the Trinimac Ruby Robe is associated with Destruction. The robes also buff your magicka regen rate to 300%.

4. You can sell Refined Moonstone to Froda Dias for 1000 gold each. You will be able to acquire it by mining Moonstone Ore (anywhere it is usually available). It can be found on Shattersky Island, but there are Sand Trolls who will be drawn to attack you if you have Moonstone Ore. If you kill them, they will respawn after a short delay, but not be aggressive. Mining more moonstone ore will make them aggressive again. You will have less of an issue when you are strong enough to kill them easily, whether that be through acquisition of levels or gear.

5. Sand Trolls also drop Chewed Moonstone Chunks, which can be combined into Refined Moonstone (4 x Chunks makes 1 x Refined Moonstone).

6. Trinimac Robes require gems (which can be mined at the Trinimac Enclave on Shattersky Island), Sanctified Leather, Ivory Ingots (which can be made at Meridia Temple, from Ebony Ingots and Leather), and Refined Moonstone to craft.

7. If you go into the Trinimac Enclave and you are not in the Trinimac Faction, you will be seen as an intruder and they will attack you. It's recommended to join the Trinimac Faction before attempting to enter the Trinimac Enclave.

8. Yes it is true, Trinimac War-Priests are able to eat an apple through their masks. I'm not sure how they do it.

9. Inside the Trinimac Enclave is a character called Garnet of Trinimac. She is their leader. If you kill her, you will be kicked out of the Trinimac faction, if you were in it. However, she drops a Garnet Crown, which you can wear. Equipping it will temporarily allow you to be considered a Trinimac Faction member while you are wearing it, but be warned, if you kill Garnet, you will enrage the Walker of Aurbis, a boss on Shattersky Island.

10. Walker of Aurbis can be attacked to make her aggressive, if you wish. Killing her will drop either 10,000 Gold or Feral Fragments. It is randomized each time you kill her.

11. Sand Trolls are resistant to Fire, and weak to Frost.

12. The Velothi Cultists on Shattersky Island worship 1 of 4 daedra: Mephala, Azura, Boethiah and Malacath. If you kill them, they will respawn instantly, and their feral fragment drops are auto-harvested. The amount you receive per kill will increase with each consecutive kill. This means if you kill 100 Velothi Cultists, you'll get 300 Feral Fragments for the 100th kill.

13. If you worship at the 4 shrines on Shattersky island, you will be removed from the Trinimac Faction and your killtracker will be reset to 0. The shrines do have some benefits, similar to the standard vanilla shrines, but slightly higher.

14. There are merchants near the daedra shrines, who can sell you Blank Scrolls. These scrolls can be crafted into equippable scrolls which each have different benefits.

15. Scroll of Azura will give you a spell that will block magical damage and reflect physical damage for 5 seconds. These scrolls are disposable, so you'll need to have quite a few to be able to use the spell repeatedly in combat.

16. The Scroll of Mephala will summon a Mephala Spider, which will spit a mild poison, and frenzy enemies into attacking each other.

17. The Scroll of Malacath will summon an Ash Spawn.

18. The Scroll of Boethiah will buff your sneak attacks to 100% for 20 seconds, but must be cast while sneaking.

19. Jyggalag Armor has been re-textured, and the sword has been replaced by one made by The Reapers' Metalworks.

20. The Mythic Dawn Outpost has 4 doors that can be unlocked with keys you can craft from Feral Fragments. Inside these doors are caves that are occupied by instant respawning, autoharvesting Velothi cultists which span 4 different levels.

Green = Level 25
Yellow = Level 50
Orange = Level 75
Red = Level 100.
