"Tess is a broker of special goods delivered to the Tower from The City and beyond."
Tess Everis is an Awoken NPC in Destiny. She delivers special order goods that come from beyond The City. Her sources are unknown but she is very reliable.
Tess vanished from the Tower around the time of the Destiny: House of Wolves, perhaps earlier. No one knew where she had gone. She returned to the Tower on 10/13/2015 and opened up the Eververse Trading Company. This is a joint venture between her and her Uncle, the guardian Fenchurch Everis.
