Guild Wars 2

I’m currently doing arah dungeon track.

If I didn’t finish the track by the time it get cycled out, does that mean I can’t do it any more till the next cycle?

And does the arah track reset at the next cycle if I didnt’ finish?

If you do Arah story, you can activate that dungeon track any time.

It does not reset, it will continue from the exact spot you were the next time it is active.
