The Secret Fusion Shrine in Steal An Egg
A hidden room, two pedestals, one rule — and the only way to get Equinox or Aetheron.
What the shrine is
The Secret Fusion Shrine is a hidden room inside the Angels & Demons biome. It is not a normal game system: there is no menu entry, no marker and no visible door. The patch notes for Update 4 said only that something was hidden somewhere in the new biome, and players found it within hours of launch.
It does one thing. You put one Light pet and one Darkness pet on two pedestals, and the shrine turns the pair into a Fusion Egg. That egg goes in your pen and hatches like any other — but the pet that comes out cannot be obtained any other way.
Where it is
| Biome | Angels & Demons — behind the 20B Speed gate |
|---|---|
| Angels side | Behind the waterfall |
| Demons side | Behind the lava wall |
| How you get in | Walk or jump into that wall until the game moves you through — there is no visible entrance |
| Inside | Two fusion pads: one for Divine pets, one for Eternal pets |
What it will and will not accept
The shrine is strict, and the strictness is the part that catches people out. It wants:
- One Light pet and one Darkness pet. Two pets from the same side do nothing. This is the mistake most first attempts make: the instinct is to fuse two Angels together.
- Both from this biome. Eternal and Divine pets from older biomes are not accepted, however rare they are.
- The same rarity as the pad. The Eternal pad takes an Eternal pair; the Divine pad takes a Divine pair. The two do not mix.
That leaves exactly two eligible pairs, which is why there are exactly two fusion results.
The two recipes
| Light pet | Darkness pet | Result | Rarity |
|---|---|---|---|
| Pegasus | Skeleton Horse | Equinox | Eternal |
| ArchAngel | World Burner | Aetheron | Divine |
Income: what this site will and will not print
Equinox and Aetheron have no developer-published income value. Some community trackers print figures for them; those figures have not been confirmed in-game, and they are the only numbers of their kind for this update. The pet tables on this site therefore list both as unverified rather than repeating a number that may not survive the next patch.
What is not published
Common questions
Where is the Secret Fusion Shrine?
Inside the Angels & Demons biome — behind the waterfall on the Angels side, or behind the lava wall on the Demons side. There is no visible entrance: you walk or jump into that wall until the game moves you through.
Which pets can you fuse?
One Light pet and one Darkness pet, both from the Angels & Demons biome, of the same rarity — an Eternal pair on the Eternal pad or a Divine pair on the Divine pad. Pets from older biomes are not accepted.
What do you get from fusion?
A Fusion Egg, which you place in your pen and hatch like any other egg. Pegasus plus Skeleton Horse gives Equinox; ArchAngel plus World Burner gives Aetheron.
Can you fuse two pets from the same side?
No. The shrine wants one Light pet and one Darkness pet. Two Angels or two Demons will not start a fusion on either pad.
