Mmm, true. Though I suppose it may depend on the Luonto a Finnish mage has? They can't walk on water the way Reynir and other Icelanders can, but Onni had no problem showing up in Reynir's Haven in owl form, so mages with bird Luontos might be able to alert people more easily. That said... either Onni needs to wake up, stat, to let them know they're walking (Taru and Trond should believe him, at least, even if Torbjörn and Siv won't?) or Reynir needs to go looking for a fellow Icelandic mage hopefully aboard the ship that he might alert to them still being alive.

Backstory, backstory, backstory! I have no doubt it'll be covered eventually, but... nowplease. D:D
