Let's meet in the evening at the "Two Trees" tavern. I want to wander around the city a bit and see what's going on. You and Knight can arrive at the tavern earlier, rent a room, and pretend to be a wealthy mage who plans to stay there for a while. If you meet this elf first, try to find out everything you can from him. We have a mental connection.
In the worst case, the agreed-upon signal is: I'll say, "The sky above Irrolan is exceptionally clear." Does that work?
