Working for the Wraithguard

Lately we have been doing work for the Wraithguard. First Seargent Aerik asked for help bringing the other races back under control by elimintating their leadership and Warden Hrosigar asked us to bring him the head of the orc shaman Sarook. After we completed these tasks, Hrosigar asked me to remove the Shade Warning Crystals around Frostcrypt. Some of the we found trapped will living crystal shards be we were able to defeat those and eliminate the shades early warning system.
We were then granted an audience with commander Haesgrin and he sent us to aid Hunter Grethmar in discovering what the new force killing his guards is. We entered Frostcrypt and waited for the new enemy. It turned out to be the corpse of Warlord Vongar. We assisted Grethmar and his men to defeat the undead giant. Commander Haesgrin also asked us to collect marks and weapons from the Shades that we killed if we ventured into Frostcrypt again.
We then met with Lodigar a reluctant Wraithguard who had been betrayed and outcast by his friends in Valdeholm. He asked us to get revenge on the 3 that betrayed him as well as eliminate many of the Seargents who cast him out. We brought him evidence of Seathir, Derein, and Gothar's shattered shields.
Our fame among the Wraithguard had allowed them to recognize us as allies and Hiemgul agreed to let us in to see the Wraithguard Lord for a price, he wanted 3 Marks of Zek. We traveled deep into Frostcrypt and killed many shades to get the marks.
