That's why I live here, rather than closer to the lamp. The smell alone might be enough for corruption. [because the smell is so strong, even nehan's iron-tight discipline wont help him not react to it. the stench of the waters sting his nose so much that he worries about nosebleeds whenever he visits that part of the district.

when he removes the syringe and caps it off, he presses a clean cotton bud to the puncture and tapes it there.]

You can remove this after an hour, make sure to dispose of it properly to avoid contamination.

[then he checks the status of the syringe, and is pleased to see that it's not red-- he harvested it properly, and now it's the signature milky color of paleblood.]
