In Godspring, there appears a winged girl.
These four demons besides Minor have been to egg world. They have made ordinary things like breakfast and computer chips and sofas and letters to their friends ("new summons didn't even offer me anything for my time, it's still really hit and miss"). One of them copied an egg person's jewelry, which may be made out of eggshell but doesn't contain any embryos.
Egg rogue does not teleport frequently and prefers to fly medium sized distances. She takes a lot of notes, or seems to - the paper appears blank or very sparse when conjured. She talked to several people. She has only been home and to Godspring and she's the only egg person who has left home.
"Yeah. We also don't have a good way to get there even if we figure out what's going on, if the sand from Minor's shoes doesn't cut it - I guess the wait time's enough that taking randoms next time they start up could do it but then we can only stay a minute and might not get anything more than sand."
"Could go wearing a sign that says 'what you're doing is incredibly dangerous please hear us out' but only if they summon another demon, last couple have been fairies."
"I do not have enough corpus to even begin to guess how to write that. Who'd the egg rogue summon, maybe hers got it..." Check. Some fairy.
"Could ask that fairy but I don't want people thinking 'oh cool another world' and then mentioning it -"
"Yeah, but that cat may already be out of the bag. Pretty eggs, totally bizarre language, new worlds are still a relatively novel phenomenon and if the fairy thinks she's the first to be there she might want to cash in on talking about it while the getting's good..."
Nod. "So summon her, try to get the language, then what if the next one they summon's not a demon -"
"Harder to get an angel or fairy on board usefully. They can't conjure the newest circle. Might have to let a few more summonses go by before we can get in. If the summoner can't read the sign and the egg rogue is not there, though, that doesn't get us much."
"She can teleport. She doesn't seem to have been teleporting around at home so far, but that could change."
"The Godspring version hedges that out preemptively just so they don't have to change it after we do Hazel."
"Yes. Where's your Hell door, is it near your sand or would you have to be dismissed and resummoned again..."
"Oh good question -"
A lot of conjuration later: "Seashells from the food she brought, apparently."
"Quite. Okay, do we have any better ideas than fetching shells and getting portaled to egg person world to... what do we even say to her? The circles are obviously for immortality, do we have to say 'your friends and family all have to die because of vague bad actors in another dimension who might hatch some of you'..."
"It's not even just that, we also really can't have them all daevafy if they all have the interdimensional teleport, and if it's transmissible we need to keep a lid on it beyond that - we could have a Vala make them unaging -"
