Hermione watches her carefully, looking concerned and apologetic. "Sorry," she says, with a rueful smile. "I've never really gotten Apparition sickness. But I've read that it's much easier the second time around."

She glances at their surroundings and pulls her wand from inside her coat; she has a particular pocket sewn into the lining for just this purpose, for the sake of easy accessibility. "So. The varieties of magic in Baedal are...numerous, but I know a few people in the cohort are from my world and would be best avoided- and who knows what goes on in other cohorts." A painful thought. Ron could be in this city, or her parents, or Luna or Ginny or anyone (she purposely doesn't think Harry because she has Sebastian, if if he's different) and she wouldn't know because of the cohort system... "There are also some basic magical facts which seem pretty common amongst varieties of magic- for example, overuse of magic will leave you tired, though different people have different limits. The very Darkest pieces of magic can destroy the caster just as easily as their target. There's often a ritual of some kind- but it might be simple." A pause as she thinks. "And the effects of magic are incredibly varied."

...bad news, basically.
