Got to say, I really like how they chose the locations for these spell-lands. For example, Jwar Isle has a locus of blue mana in the volcanic crater in its center, and no explorer has ever returned from it.
I really wish the french name translated to "Perturbing Jwar" or "Jwar Perturbation". Disturbing sounds like Nys Dal is coming to Jwar Isle, knocking on the wall, "Hi, can you tell me where the roil is?". Perturbing is such a more forceful word, like ringing the door bell 15 times, until the denizens of Jwar are forced to answer "Hello, have you heard of Heliod? We have these scrolls showing you his love for you and how if you don't believe you will go straight to the underworld. And I'm talking about Phylias, not Ilysia. Can we count on seeing you at temple this Sunday?"
