Unable to leave Eastern Plaguelands

Started a DK, leveled to 15 and ran out of quests. I can’t travel past eastern Plaguelands due to an invisible wall. there are no NPC,s from Tyre to Plaguelands. Please fix or advise. Thank you!

did you do the battle for lights hope chapel?

Believe you have to complete the quest line and it should end at a chapel just west of Archerus where you are freed from the Lich King’s control after he’s defeated by some paladins or something.

that light hope battle takes awhile to reset once its over like 30ish mins wait time. tho it may be shorter now
