Who knows what that guy is capable of? If he is a Sindar, he could be capable of many True Rune-related things. It's still unlikely, but not absurd or anything.
Well he was probably more of a projection of a Sindarian then an actual one.Using their power from a distance to create the fog ship and the ship's guide taxed the Sindarian's power. Which is why he needed an impossing appearance and a true rune. Most of his power was used to create the ship for gathering runes.
If he is a Sindar who knows if the guide was his actual form or a projection from some place very far away.
yeah there's too many unknowns for us to be sure of anything.. we can only hope we see the fog ship guide again, then maybe some of our questions will be answered
And from Leknaat's discussion with the Fog Ship Captain, he was a flunky, a tool who had a specific purpose who "malfunctioned" and then she destroyed.
