Connection: Choose one of the following.
1. Pick one other PC. This character knows a little something about void matter, or at least claimed to at one time.
2. Pick one other PC. You are friends, and you’d hate to see this character harmed.
3. Pick one other PC. They don’t understand the danger your void matter represents.
4. Pick one other PC. They were exposed to void matter, the same as you, but didn’t become infused with it. You think they might be immune.

1. Pick one other PC. This character knows a little something about void matter, or at least claimed to at one time.

1. Pick one other PC. This character seems able to use all the objects and structures you craft with ease, even when you hide how to access certain functions.
2. Pick one other PC. This character knows a few things that can help when the objects or structures you crafted need repair.
3. Pick one other PC. This character has a special tool that you think would be perfect for your own set, but they regard it as a keepsake or are otherwise reluctant to give it up, even though they don’t seem to know what it’s good for.
4. Pick one other PC. When you were developing a plan from a seed of knowledge from the prior worlds, this character was burned in an unexpected incident. They still
have a small scar.

3. Pick one other PC. This character has a special tool that you think would be perfect for your own set, but they regard it as a keepsake or are otherwise reluctant to give it up, even though they don’t seem to know what it’s good for.

Pick one other PC. This character believes that you cured someone close to them of a deadly disease, and they are grateful. You aren’t sure whether you actually helped or if that person wasn’t as sick as was thought.

That would absolutely be Radwa - between their books, their prior studies, and their parents' tutelage, Radwa would know or have access to some knowledge about void matter, scant as it might be.

So I'd actually to use the Initial Link from a different descriptor:

• One of the PCs is your sibling, and you came along to watch out for them.

Agatho, if I'm getting the vibe of your character correctly, I think it would make a lot of sense if Derrick were your (much) younger sibling. I see Derrick as a very devout person routed in tradition and devoted to a code.

Agatho is a native of Hayrest.  His parents perished before he was old enough to remember them, and he was taken in by an orphanage run by the Church of the Sovereign One.  Recognizing his psionic gifts, they provided training from an early age.

His faith is based strongly on a rare surviving echo of Calvinism, including a vague distrust of those associated with a Pope.  The Sovereign One created all, and rules over all.  All proceeds according to The Plan, yet all answer for their choices in The Plan.

Motivations include serving the Sovereign One, serving and healing those around him, exploring the world around him, learning tidbits about the past, and acquiring interesting abilities/technologies/etc.

The Church possesses an ancient artifact that is able to telepathically transmit their ancient records, including their Sacred Scriptures, as if someone was reading them aloud, and they are comprehensibly perceived in the mind of the listener regardless of any language barriers.  Thus, their writings have survived, preserved even through the passage of time and changes of tongue.

As part of each member's training, they create their own book, writing their own copy of the ancient records as telepathically dictated.  Agatho has his own copy, which is his most treasured possession.

Members spend periods of time alternating between serving in Hayrest and sojourning elsewhere to serve the physical and spiritual needs of a lost world.  Agatho is currently sojourning.

Could I take this instead, Agatho?

Let's work with this; from the sounds of things, you may have passed through Stirthal on the way to the Black Riage

I like this one: "Pick one other PC. This character seems incredibly unaware of their body and always happens to get in your way. If you miss your foe and accidentally hit someone else in close range, it's likely to be them."

Mayhew and Hoa may well be learning from each other as students, having trained under vastly different circumstances.  They'd have met little, if at all, given Mayhew's current location (Coming Soon!).  Hoa's likely heard of him, though.

Just a thought.  If it doesn't work, no worries.

Mayhew, I'm not sure about any of the formal connections, but as a resident of Canthus you'd probably be aware that Radwa's building a four-wheel drive transport cart for the expedition and is short on a few parts.

I volunteer for Initial Link #2, or a combination of #2 and #3, if you wish...  :)
