[pnpgm] Comment re healing + short intro

[Alex Koponen]

Seeing the tall elf moving to heal folks Z'leyra mentions "Since magical 
healing triggers an extra natural healing, I find that using non-magical 
means to improve the wounded person's natural healing ability is best 
done both before and after magical healing. Doing it before helps the 
triggered healing and after helps the regular overnight healing. Of 
course if the wound is minor either way should work adequately by 
itself."

She introduces herself <speaking Elf Sidh> "Hello, I am Z'leyra." She 
smiles "I see that you bring excitement with you."

To the party she suggests "If we want to stay in this camp more than a 
few hours we might want to have the horses drag the giant's corpses 
further away. Or we can move our camp a bit. At daybreak we can track 
their footprints back to their lair."
