Thanatos opens his golden eyes to stare at Idia. "As long as it's legible, the SCP should allow others still on the train to read it. We've received written material from others and can somehow read it regardless of language. I'm not sure how my records world be any different." If the others want it transcribed into another format, then... that can be an effort for them to undertake. The information would still be there in a readable format... as Thanatos understands it. (Language is always a bit weird for gods. Death doesn't stop just because someone speaks something different.)

"We both have reasons we cannot stay on the train, and if someone tries to search for my world... Well, I'll still be around by the time someone does." He's not mortal. He's Death Incarnate. Unless there is no life left on his world, he'll have a reason for existing. "Yondu has those to find first, and I have a world to set right before I can think of doing anything else."

Also, he still needs to deal with the mess he, Zagreus, and Persephone caused in the Underworld. Mort squeaks something, and Thanatos frowns. "No, I do not recommend trying to run into Lord Hades's ankles. Besides, your chariot will likely stop working if we bring it."

Mort, Mort please don't attack Lord Hades....
