Did you heal both soldiers in Aleroth? If not, Goemoe will not give you lizard teleporter scroll. However, it only activates one teleporter pad, which is in an area you will not likely need to return to after you have cleared it. That scroll is not needed for the quest to activate the teleporters.
The human scroll you can get by continuing with the escort quest and agreeing to work for the army, or by looting the cursed abbey. The elven scroll you can get from the only elves in the Rivertown area (ie before heading to the Dark Forest).
