Ragren the Vigilant

Ragren the Vigilant is a Lesser Deity in Tebrith. Specifically, he is one of the Guardians of the Shards. According to the rhyme, she is the "One in Frost".

He's a Duergar Rogue, who has been given the Shard by Muirmas. While he holds the shard, he cannot pass through the portal to the Underdark, which is actually a demi-plane, rather than just a regular underground network. Drow regularly pass through, as they are more exploratory, but for the most part other Duergar stay in the Underdark.

Ragren is incredibly wizened and ancient, and he mostly doesn't move, sitting directly in front of the portal with the shard kept in his hands. When pressed, however, he springs to life, sporting a shockingly youthful appearance. He wears beautiful, stained black leather armour, and weilds a simple looking crossbow, though it is enchanted. If a fight has broken out, he can disappear almost effortlessly into the shadows of the dark tunnels he resides in, making him a force to be reckoned with.

He can be found in the tunnels underneath Hjaldar, the entrance to which is guarded by Molvayas in The Wenches Entance.
