There are two errors here.
“I know that the purification is important, but if we don’t save those poisoned farmers right away, we may lose our lives.”
This line should be talking about the poisoned farmers, so the last part should say “they may lose their lives.”
The next line, “As a druid, how can I move those people out?” should probably have another look taken at it. I suspect the original text said something more like “As a druid, how can I leave those people out/behind” or in some way basically saying that, as a druid he can’t leave them to die. Should definitely get another look.
