Dunveri Rodrun of Ouada
He is probably meant to be a caravaneer since he is on the gang plank to his ship.
He does not offer the "Travel" option.
His greeting includes:  "Care to see the sights? Where can I take you?"
His "trade" option says: "I'm a shipmaster. I can transport you by ship to various destinations for a modest fee."
His  "destination" option contradicts that:  "I transport wares from Tel Ouada to many places on board my ship 'Wave Render'. No personal transports, not even for a %PC_Class%.
His wiki page says he provides transport to Firewatch and Bal Oyra.
---------------
It seems excessive to deny transport to the PC when the PC is not a member of House Telvanni and does not have the quest Books of Faith, just because the disposition is maxed.
It should not be necessary to disable the travel option until after the quest is active; or perhaps it should not be necessayr at all.
