Skeldar

Skeldar was a member of the Original Group, who were the party of the Lost Mine of Phandelver campaign and was part of the trio hired by Gundren Rockseeker to deliver supplies to the town of Phandalin during the first session of LMoP. He was played by Shmexi.
He is a tiefling warlock and the faithful companion/uncle figure to the half-orc barbarian Gogdor, whom he took into his care whilst at a young age. Not much is known about Skeldar as he was very seclusive and kept to himself whilst practicing his magic, gaining knowledge and probably judging everyone else.
He was slain by the Russian Lady during the final session.
