Although it seems like quite a long time has passed, in reality, it's because the development speed of Deepwater City is too fast, and the moves of both sides are quicker than each other... There's no way, when deities in disguise make a move, even if they seem evenly matched, you have to pay extra attention.
After all, divine power can sometimes be unreasonable.
And it's not Kelben who stayed there; even the Northern Seven Sisters, however fearless, wouldn't risk their own younger sister.
So the timing for the Undead Tribe to go to Icewind Valley was rather fortunate; several bald high-level Red Robe Mages are blocking Kelben, and it seems they've tested each other a few rounds, but haven't yet started the main course.
As for Marko, who should be Kelben's revenge target... Hill looked up and down and couldn't find the Archmage who is always in white, always looking empathetic.
