Then this key must be thrown away somewhere no one will find it.
There is a small sulfur lake at the mine in the north.
The lake is full of all sorts of corrosives so the key should disappear without a trace.
You must remember! No one in the world can know of what you're doing.

There is a small sulfur lake at the mine in the north.
Throw this key into that lake.

It's a relief that the key and the trial upon us is over.
I do not know how to express my gratitude to you in words.
You have given Valencia a new future.
I shall repay you for your kindness someday.
