I don't know when Kallixta hit level 23 as it was already that before logging in. Again the point went into Diving Strength.
I trammed up to Ironforge to get the start of the Level 20 Paladin quest. Part of its chain is running Deadmines, Shadowfang Keep and other dungeons, so I wanted to get started before they disappeared from LFD. It meant I spent time riding around for both this and a couple other quests, to Northshire Abbey and Redridge.
In chat, I talked about "commuting". It seemed odd returning to Ironforge. Kallixta appears to feel more at home in Elwynn Forest, although she was disgusted at the slovenly habits of human librarians. There were books left on the floor both in Stormwind Keep's library and at the Abbey. It mades it difficult to be [Well Read].
Next steps: visit Daphne in Westfall (and protect her from attack) and reattempt the traitor escort. There's another tram ride to Ironforge before being ready for a 2nd run of DM. There's also a quest to pick up in Auberdine before BFD.
