Level 2: Tier 1E

Tier 1E: The "calcium carbonate" puzzle

Tier Overview

On March 2nd, fishxw found that Rob updated the Tier 1D page with the image “THE_FINALS_OSPUZE_AD_bonus_candy_02.” On March 3rd a higher resolution of the image was uploaded to the official-art channel with the name “THE_FINALS_OSPUZE_AD_bonus_candy_02_higres_per_EE-hunters-request” and the hidden metadata message “Hi EE-hunters.! There is nothing hidden in this image (just the start date of the next tier) , you are on vacation.! From Embark with love.!”

Along with the image was a timer, counting down until the end of the hunter's vacation and the start of T1E.

After 21 days of rest, the hunters were eager to start T1E. On March 23rd, Rob said, "I thought you might say that…therefore I actually DID hide a couple of things in some of the assets I uploaded during your vacation…so if you are bored and can’t really wait until Monday… there is one diamond and a primary clue out there, waiting to be found…" After learning that there were, in fact, clues hidden in the image, the hunters started searching. All that has been found in this image is the countdown to the end of the EE-vacation.

On March 27th, Rob took down the countdown on the T1D page and posted an official artwork called "THE_FINALS_Wallpaper_CB_Up_We_Go_2880x1620” with the hidden metadata message “Hi there EE-Hunters.! Good luck have fun... from embark with love.!”

A single pixel in the top left corner stood out, and had a hexcode of #206888.
The text on the sign in the background was coordinates for Torslanda, a town in Sweden.
More hidden numbers revealed coordinates for the River Moriston in Scotland.
An MD5 hash hidden at the bottom of the image was decoded to the number "206888"
A cross cipher was discovered in the footer.
The character's weapon charm was confirmed to be a T-Rex.
A snowflake was hidden in the left side of the image.

On March 31st, Rob posted the image "THE_FINALS_Kynezantama," a Byzantine-themed Nama Tama requested by Kyne.

Nama Tama wore a crown with pearls and jewels on it
Another hidden snowflake was found in the image.
The letters T, U, R, A, H, and R were found in the jewel of the crown.
The letters T, O, R, S, N, O, and R were found near Nama Tama's earring.
The two series of letters were unscrambled to the name Arthur Rostron, the captain of the RMS Carpathia.
The logo for the White Star Line was hidden near the bottom of Nama Tama.
Images of Ammonoids were hidden in Nama Tama's cheeks.
The #206888 pixel was found again in the image.

One week later, on April 7th, Dusty posted the image "THE_FINALS_Robatama" which was a Nama Tama dressed as Rob himself.

Rune symbols in the eyes and cheeks spelled "KARI"
A series of boxes was discovered that were converted into binary. It was decoded into "s/2006 s 2" which was the reference number for the moon Kari.
The #206888 pixel was found again.
Seemingly random scribbles in the dark parts of the image were pieced together to form a graph, similar to the graph of effective potential.
The string "512006 5 2 120013130A171100" was found on the OSPUZE can, and was decoded into "s/2006 s 2" again.

At this point, there were many theories being thrown around in the Discord, but none of them seemed to have any solid connection. On April 15th, Rob posted the image "THE_FINALS_Wallpaper_Iseult_Chill_2880x1620"

Another snowflake was found in the image.
A series of pink pixels on the edge of the ISEUL-T logo were decoded to the numbers 46, 11, and 94.
A hidden QR code was found that led to an image of a record. The name Raija Mannarla was removed compared to the original version.
Warped text was discovered, reading "KARI"
A partial image of a diamond and a sun was found. The diamond was discovered to be the Hope Diamond, and the sun was a part of the flag of Louis XIV.
A picture of an iceberg was found in the background of the image.
The Greek word "ΠΕΝΘΕΣΙΔΕΙΔ" was found, and translated to Penthesilea, the queen of the Amazons.
The code "L 24 239 MH19 64PLC 012971" was found, which is the corporate code for the company Proctor and Gamble.

After these clues were discovered, many theories were either solidified or thrown out the window, but the hunters still needed to find a strong connection. On April 22nd, Rob posted the image "A_Space_Friend" with metadata, "Hi there dear EE-Hunters.! Hope you a934å¨”/Ä*I=Y#RI? *** THIS MESSAGE HAS BEEN COMPROMISED ***"

The green can in the image is the cleaning agent Comet, produced by Proctor and Gamble. The main ingredient in Comet is calcium carbonate.
The small label on the camera device has "P.ID #9173" on it.
The latches on the bottom of Nama Tama's suit have the labels "325CC" and "275CC."

The hunters knew that the Comet product must be important, because of the previous clue for Proctor and Gamble. The hunters thought that the name of the product, Comet, might be the main idea of this clue path, similar to 1064 Aethusa comet from T1A. It wasn't until later that the connection was made between the actual composition of the product rather than its name. On March 3rd, Rob posted "THE_FINALS_Namabatama," likely referencing Discord member, volunteer moderator, and bat-lover, Kunai. It has the metadata, "Hi th "#¤/0/! THIS MESSAGE HAS BEEN COMPROMISED"

Two more snowflakes were hidden in the ears, one in each.
Stalagmite-like shapes were found in the top corners of the image.
Pixels found around the border of the image were found, which were converted to the number sequence 2, 14, 16, 4, 2, 2.
A swirl of numbers was revealed around the image, counting up from zero to 18.
Three lines with varying width and height were found.

Clues 3, 4, and 5 were never solved, and the two other clues didn't seem to form any connections. As the hunters struggled, Rob posted an unofficial supplementary image featuring Saint Esbjorn and Saint Dusty.

Solving

On July 1st, DEV64! entered the correct password "cacoiii" and unlocked Tier 1E. This tier took a total of 96 days to solve.

Summary

All the snowflakes, diamonds, and geology-related clues pointed towards the chemical compound calcium carbonate. Various clues pointed to Latin, including the passwords from previous tiers and Tier 1E image titles. Combining the two main clues of calcium carbonate and Latin yielded the final password: the chemical formula for calcium carbonate, CaCO₃, but with the 3 replaced with Roman numerals, cacoiii.
