Fallen Earth Chips, Fallen Earth gold

Go to the farm and get your arrows and your kill count first. (You can do Death's Challenge whenever.) After you return the horse by dismounting it next to Salanar the Horseman, he will give you the follow-up Fallen Earth gold quest Into the Realm of Shadows, which is your first real taste into the instancing of the zone.

Run down into where the Haven-shire stables were and try to engage a Dark Rider of Acherus. Defeat him and mount his horse to take it back to Death's Breach. Salanar will join you in the shadow realm, congratulate you, and tell you to speak to him outside it.

Towers - destroy it and get rewards: During the siege of Winter-grasp, the defenders should consider mounting an assault of their own. For each of the attacking team's towers that they manage to destroy, the defenders will be rewarded with bonus honor. Remember, a good offense is a great defense.

PvP Flagging - flagged to PvP once you enter: Once you enter Winter-grasp, you will automatically flag for PvP, even on a PvE realm. If you do not wish to engage in PvP combat, either wait for the relatively quiet cool-down period to begin, or stay out of the zone entirely.
