Wow, I haven't been keeping up with the OOC thread often enough!
Cure Light Wounds is superior to Aid the Wounded because it does not require the recipient to spend a healing surge to gain the healing. In addition, it can be used to cure any creature, and not only allies.
Now, how does a cleric from Tyrborg wind up in the Strand? Well, the most direct way is the water route across the plaguelands. It requires navigating that huge swamp south of the Sea of Qashya, and making a couple of portages across the low mountains surrounding Tawaren. At some point, though, the Stoutwater is going to turn unnavigable. By that time, you might have started to encounter enough hillfolk and Stoutlings willing to help you across the Uzuids and on down to the Coriander Coast, where it should be easy to find a ship to Port Magalie and upriver.
And yes, the mage definitely does need protecting. I really thought I was going down again already!
