In a desperate, end-of-the-world attempt to come up with something that will help save the people of Arx when Azazel and his Abyssal share army come for the Thinnest Point, Medeia gathers the best magical and alchemical minds she can think of to do something Medeia /doesn't/ do: make poison.

Having had luck in the past - before crossing the threshold! - with creating targeted tools against specific threats (like Thornweave Fire and the talismans that protected against the Horned God's magic), she sets out to create something that will specifically harm Abyssal beings. She's not even sure what this is going to take. But she's going to TRY. The blood of Godsworn? Nethicite? She'll clear-cut her gardens if it helps.

After some discussion about collateral harm and intentionality, the hope is that, if successful, the poison should be something that can be coated on the weapons of defenders, perhaps coated upon their armor, and set in strategic traps (near the Thinnest Point?) that can be deployed to great effect without potentially harming allies.

Mabelle is not foreign to experimenting with all those elements. Metals with primum, odd plants, gemstones, her own blood and the time she spent in the Lyceum. Time to mix and try not to die of the explosion.

Galatea's skill at alchemy has few equals. Be it poison, unnatural herbs created during the Platinum Shift, nethicite, or even the blood of the faithful, there are plenty of avenues to take in research. The ritual (revelation 52) of Striking Through the Mirror contains certain techniques for targeted strikes against individual demons, but perhaps it might also provide clues as to more general patterns for substances that threatened demonic lives.

Thea knows about alchemy. A lot about alchemy. Poison. A lot about that too. She will use her knowledge as well as a touch of something else to help aide in the the cause. Thea has her own special additives afterall.

Eirene is an expect occultist. Even without her magic she knows what she's doing with rituals, as well as having knowledge of alchemy. So trying to craft something which harms the enemy isn't too farfetched.

Poison is not Mirk's specialty, but he's worked on the Thornweave poison before, and he helped bind Azazel as well, once upon a time (Action 2936 & Clue 2925), and he knows the rite to hide knowledge from the Despite (Revelation 34). So he draws on that pool of knowledge to attempt to devise something, anything that can harm Azazel. He's in a supporting role, providing advise and knowledge, and perhaps some primum towards a shared ritual, if he needs to.

If it weakens their enemy, even slightly? It's worth it.

So while Mia is no alchemist, she does have an extensive knowledge of the occult. Even more than that, she has a small orichalcum figurine that has long acted a shield against the Abyssal entities controlled by her father, protecting her from their sight and their assault. While she won't offer it up as an ingredient, surely it can provide some helpful insight through.... uhhh... inversion! Yes, inversion. If her figurine protects the wearer from the Abyss, then surely the inversion of some of its properties might help a person attack the Abyss. That makes sense. That totally makes sense. She'll just be standing waaaaaaaay over there while the alchemists test this theory out.

Aco will help, she's only soso with Alchemy but she's got a lot to controbute to a poison. Especially when armed with a bit of magic.

Lianne has spent the majority of her adult life studying the Abyss and its denizens, including a stretch of years specifically focused on how shards are formed. She is uniquely qualified to assist with this project and will focus her efforts specifically on concocting a poison especially effective against shards that this project might drastically reduce the hordes' horrifying numbers. She may be able to provide a shard, if the team would benefit from having a test subject.

That 'blood of a Godsworn' she was talking about? Is me!

Caspian may not know poison or magic very well, but he does know weapons and abyssal. He is quite proficient with the stabbing of and being stabbed by abyssals. There is a trick to making a blade coating, to viscous and it simply drips off, to gooey and it doesn't infect the sight. he offers his insights into weapon coatings as well as how best to fight abyssals and get the poison into their system.

Did someone say poison? Not that a Velenosa Prince who has somehow survived into his sixties would know anything about poison. Okay maybe he knows a little. And maybe he knows a little about the occult. Just maybe. And what little he theoretically does know he uses to help the Lady Medeia with her task.

Mirari is skilled at making poisons, it's something she knows a great deal about and has expert knowledge on. It's more than just alchemy, Mirari herself creates poison through magic. Mirari is also a master weaponsmith and will craft weapons specifically for this cause, seeing if there are ways to alter the weapons design to better hold the poison itself. She will focus all her skills into developing something powerful and effective.

Noah knows all about poisons. He even knows about customizing them. Using them as needed. Dosing people at parties to experiment how they work out. He even knows a few secrets here and there to make them more potent. He is more than willing to lock himself away and study it day and night. He's more than willing to assist. He's more than willing to help come up with a way to help out.

Agric may not be an alchemist, but he does know the occult and is an excellent scholar. He's going to spend time researching anything and everything that may be of use in developing this concoction, focusing on texts relating to the Abyss and similar matters of the occult.

Olivia is going to use her gift with plants to try and rush some hybridized plants that may have a greater impact on Abyssals, with the hope of creating a plant that can have extracts harmful to the intended targets.

Tamsin is not an alchemist, but she is a physician and an invoker. She will lend her necromancy powers to the experimentation, adding death energy to anyone's experiment that wants it. But her real contribution to the effort is going to be in providing leadership! She's going to help arrange lab schedules and coordinate assistants. She'll provide cheerleading to keep people interested and motivated. When things are caustic to touch, Tamsin lends her skeleton pal to carry them around. In short, she'll lead how she's been groomed to lead: by pitching in everywhere there's a gap.

Titania is not good with postions or plants. But what she is good at is talking to people and diplomacy, so she will help get materials. She will talk to those she has to, sit and explain how important this project is.

Raven helps Medeia by letting Media test the potion on one of Raven's spare weapons making sure it adheres to the blade, isn't a hazard to the wielder and so on. Additionally if there is time, Raven will try live testing the weapon with Caspian by finding a low level (non friendly!) demon like a wraith suitable to test the blade on to try to verify the effects.

It did kill a tremendous amount of shards, and certainly was successful against abyssal creatures. Whether the traps in the the catacombs did some good against Azazel is harder to say, but it likely slowled him down, considering he didn't immediately cross into the Thinnest Point.
