My OH my! Seems like you’ve just been kidnapped and brought to an extremely Secret Club underground — a rigid yet well-structured society that guarantees luxury and opulence to its members: promising access to ALL the wealth of the Earth!
you’re their newest potential member, but the process of joining is not easy at all (if it were, then we wouldn’t be dealing with extreme global wealth inequality, but that’s a story for another time).
those old, scratchy-voiced leaders only gave you these numbers to decode your new name:
10 5 4 1
8 6 5 10
you’re stumped for a few minutes, but suddenly everything made sense: because fortunately, you are as enthusiastic about the field of [redacted] as you are about fighting for the plight of the oppressed masses.
“it’s •••• ••••!” you exclaim. “and that is a terrible name!”
and it is a terrible name — but you claim it, you join their stupid club, you clean out the society of its wealth, and you use the money to blah blah blah basically a happy ending for everyone (except those dodgy old stooges).
What was your new name?
Note: There is only one step that requires external knowledge (in the field of [redacted]). All additional clues pertaining to [redacted] were given through this post. If you figure out the additional clues, you will know what EXACTLY to search for.
Regarding the edit (solution spoiler):
I am aware of the formatting and capitalization rules. The uppercase letters spell out MOHS SCALLE, hence the deliberate lowercase letters. Basically the suggested edit removed these, which I agree may not be the most significant of clues, but may have helped someone nonetheless.
