The following document was discovered in a sealed container within the Tier 5 residential apartment of Henrik Calder-Osei, a retired pharmaceutical logistics executive, during routine post-mortem property clearance on November 2, 2224. Calder-Osei died of natural causes on October 28, 2224, at the age of 87. He had no surviving children, no designated heirs, and no will on file. The container was a fireproof document safe, biometrically locked, which required override authorization to open. The contents consisted of a single handwritten letter.

"To myself, when I am small again. If you are reading this, the procedure worked. You will not remember everything immediately — they said the first months are disorienting, and the new brain needs time to integrate the patterns. Be patient with yourself. You have done this before, even if you don't remember doing it.

The following information is essential for recovering your previous life's assets: The primary account is held at Meridian First Federal under the name Calder Trust, account designation CF-7791-ALPHA. Access requires the passphrase 'the river remembers its source.' Secondary holdings are distributed across four shell entities registered in the Detroit Autonomous Collective — the names and access codes are in the second safe, third floor, northwest corner of the apartment you are currently inheriting from yourself.

Contact Dr. [REDACTED] at the [REDACTED] clinic. The address is [REDACTED]. This clinic does not appear in any public directory. You found it through [REDACTED] in 2221. They will have your follow-up protocol. Do not skip the cognitive integration sessions — last time you skipped them and lost eleven months of procedural memory.

You will be frightened. You will feel wrong in your body. Your hands will be too small and your voice will be too high and you will dream of being old in a way that feels more real than being young. This passes. By year two, the body feels like yours. By year three, you won't remember what the old one felt like. Trust the process. Trust yourself. You have the rest of a life to live. — H.C.O."

The letter is written in handwriting confirmed by forensic analysis to be that of Henrik Calder-Osei. The account referenced at Meridian First Federal exists but is sealed under fiduciary lock. The apartment contained no second safe. The property clearance team filed the letter as an artifact of cognitive decline. No further investigation was conducted.
