Resting outside the cave restores SP only (requires Woodsmanship). An engraving south and west of the cave entrance contains the words "Tallys was here", you add your name after your first run and the somewhat ominous message "and so was I" will eventually be added. While exploring you may find one random loot drop from skeletal remains. On subsequent runs instead of the ogre it will be a Forest Troll, combat to be documented. The final reward is either 32 or 64 General XP at random and some Loot.
