Door of the Dead only works between a point in the underworld and the same point in creation, by the way.  It can't actually be used to speed up travel.  (except in allowing you to avoid the annoying hike to a shadowland)<br/><br/>It also saves the party a lot of trouble with having to pop out at thorns and then walk to lookshy, instead of being able to just appear in the middle of the city.  (or outside and hoodwink the guards, if you'd rather have a better cover story)<br/><br/>Forging papers might be a worthwhile activity to do on the way over.  Knowing what sorts of paperwork local authorities in Lookshy will expect is a difficulty 5  Intelligence + Lore check.
