if you recalled the lore from this game, you'd know that the gods, before many of them 'cut off' norrath from thier power, gave visions to various members of the races leading them from thier homes to Qeynos/Freeport. particularly the 'good' gods so there would be forces in place in Qeynos/Freeport. they knew they were cutting off teleportation, and no one trusted Rallos not to go ahead with his 'world war' plan of action from the council.
while the gods didn't plan ofr or expect the Rending...giving them visions and moving many/most thier races to the major two cities prolly saved some of them from outright extinction. including the Koada'dal, who would all be puppets of Mayong/xenophobic fanatics now if they'd stayed in Felwithe(New Tunaria). the Halflings would all be Shadowedmen vessels. the gnomes nearly extinct after thier Skynet situation with Klak'Anon. the Iksar would all be dead or under Sathirian rule. the Ogres that survived the Greenmist, other then the Thullosians, were the ones allied with Freeport during the war. the Trolls would all be dead or shadowed puppets or member of the Brokenskull clan...who are ruled by shadowed puppets.
the Barbs woudl have died ut/nearly so at the sacking of Halas. only a few of them made it out as it was to qeynos/freeport. the Kerra would all have been trapped in Ultera, along with all the Erudites.
and besides, if Tunare herself says 'go to Qeynos' most Koada'dal I imagine who got the memo, listened to it.
